Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497162, here are decompositions:

  • 5 + 31497157 = 31497162
  • 23 + 31497139 = 31497162
  • 29 + 31497133 = 31497162
  • 79 + 31497083 = 31497162
  • 173 + 31496989 = 31497162
  • 199 + 31496963 = 31497162
  • 241 + 31496921 = 31497162
  • 353 + 31496809 = 31497162

Showing the first eight; more decompositions exist.
