Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497952, here are decompositions:

  • 11 + 31497941 = 31497952
  • 23 + 31497929 = 31497952
  • 89 + 31497863 = 31497952
  • 149 + 31497803 = 31497952
  • 179 + 31497773 = 31497952
  • 251 + 31497701 = 31497952
  • 281 + 31497671 = 31497952
  • 383 + 31497569 = 31497952

Showing the first eight; more decompositions exist.
