Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497304, here are decompositions:

  • 5 + 31497299 = 31497304
  • 11 + 31497293 = 31497304
  • 17 + 31497287 = 31497304
  • 53 + 31497251 = 31497304
  • 233 + 31497071 = 31497304
  • 347 + 31496957 = 31497304
  • 383 + 31496921 = 31497304
  • 431 + 31496873 = 31497304

Showing the first eight; more decompositions exist.
