Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537510, here are decompositions:

3 + 31537507 = 31537510
29 + 31537481 = 31537510
41 + 31537469 = 31537510
101 + 31537409 = 31537510
197 + 31537313 = 31537510
239 + 31537271 = 31537510
281 + 31537229 = 31537510
359 + 31537151 = 31537510

Showing the first eight; more decompositions exist.
