Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446360, here are decompositions:

  • 19 + 31446341 = 31446360
  • 31 + 31446329 = 31446360
  • 37 + 31446323 = 31446360
  • 103 + 31446257 = 31446360
  • 107 + 31446253 = 31446360
  • 109 + 31446251 = 31446360
  • 131 + 31446229 = 31446360
  • 137 + 31446223 = 31446360

Showing the first eight; more decompositions exist.
