Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499524, here are decompositions:

113 + 31499411 = 31499524
137 + 31499387 = 31499524
197 + 31499327 = 31499524
227 + 31499297 = 31499524
233 + 31499291 = 31499524
257 + 31499267 = 31499524
293 + 31499231 = 31499524
461 + 31499063 = 31499524

Showing the first eight; more decompositions exist.
