Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147401102, here are decompositions:

  • 3 + 2147401099 = 2147401102
  • 281 + 2147400821 = 2147401102
  • 359 + 2147400743 = 2147401102
  • 419 + 2147400683 = 2147401102
  • 479 + 2147400623 = 2147401102
  • 503 + 2147400599 = 2147401102
  • 653 + 2147400449 = 2147401102
  • 773 + 2147400329 = 2147401102

Showing the first eight; more decompositions exist.
