Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147401090, here are decompositions:

  • 113 + 2147400977 = 2147401090
  • 269 + 2147400821 = 2147401090
  • 347 + 2147400743 = 2147401090
  • 467 + 2147400623 = 2147401090
  • 491 + 2147400599 = 2147401090
  • 641 + 2147400449 = 2147401090
  • 761 + 2147400329 = 2147401090
  • 797 + 2147400293 = 2147401090

Showing the first eight; more decompositions exist.
