Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499796, here are decompositions:

137 + 31499659 = 31499796
197 + 31499599 = 31499796
337 + 31499459 = 31499796
389 + 31499407 = 31499796
397 + 31499399 = 31499796
409 + 31499387 = 31499796
467 + 31499329 = 31499796
487 + 31499309 = 31499796

Showing the first eight; more decompositions exist.
