Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584976, here are decompositions:

  • 3 + 2147584973 = 2147584976
  • 109 + 2147584867 = 2147584976
  • 283 + 2147584693 = 2147584976
  • 307 + 2147584669 = 2147584976
  • 367 + 2147584609 = 2147584976
  • 373 + 2147584603 = 2147584976
  • 379 + 2147584597 = 2147584976
  • 457 + 2147584519 = 2147584976

Showing the first eight; more decompositions exist.
