Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496728, here are decompositions:

59 + 31496669 = 31496728
191 + 31496537 = 31496728
239 + 31496489 = 31496728
311 + 31496417 = 31496728
359 + 31496369 = 31496728
467 + 31496261 = 31496728
509 + 31496219 = 31496728
587 + 31496141 = 31496728

Showing the first eight; more decompositions exist.
