Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499696, here are decompositions:

37 + 31499659 = 31499696
97 + 31499599 = 31499696
103 + 31499593 = 31499696
199 + 31499497 = 31499696
229 + 31499467 = 31499696
313 + 31499383 = 31499696
367 + 31499329 = 31499696
373 + 31499323 = 31499696

Showing the first eight; more decompositions exist.
