Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514752, here are decompositions:

11 + 31514741 = 31514752
89 + 31514663 = 31514752
173 + 31514579 = 31514752
179 + 31514573 = 31514752
239 + 31514513 = 31514752
443 + 31514309 = 31514752
461 + 31514291 = 31514752
491 + 31514261 = 31514752

Showing the first eight; more decompositions exist.
