Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497596, here are decompositions:

19 + 31497577 = 31497596
37 + 31497559 = 31497596
73 + 31497523 = 31497596
127 + 31497469 = 31497596
283 + 31497313 = 31497596
313 + 31497283 = 31497596
367 + 31497229 = 31497596
373 + 31497223 = 31497596

Showing the first eight; more decompositions exist.
