Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623308, here are decompositions:

  • 97 + 31623211 = 31623308
  • 109 + 31623199 = 31623308
  • 127 + 31623181 = 31623308
  • 139 + 31623169 = 31623308
  • 349 + 31622959 = 31623308
  • 499 + 31622809 = 31623308
  • 709 + 31622599 = 31623308
  • 919 + 31622389 = 31623308

Showing the first eight; more decompositions exist.
