Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517254, here are decompositions:

11 + 31517243 = 31517254
23 + 31517231 = 31517254
47 + 31517207 = 31517254
191 + 31517063 = 31517254
227 + 31517027 = 31517254
233 + 31517021 = 31517254
281 + 31516973 = 31517254
443 + 31516811 = 31517254

Showing the first eight; more decompositions exist.
