Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537514, here are decompositions:

7 + 31537507 = 31537514
37 + 31537477 = 31537514
241 + 31537273 = 31537514
271 + 31537243 = 31537514
313 + 31537201 = 31537514
367 + 31537147 = 31537514
487 + 31537027 = 31537514
523 + 31536991 = 31537514

Showing the first eight; more decompositions exist.
