Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614492, here are decompositions:

43 + 31614449 = 31614492
139 + 31614353 = 31614492
149 + 31614343 = 31614492
263 + 31614229 = 31614492
281 + 31614211 = 31614492
293 + 31614199 = 31614492
311 + 31614181 = 31614492
313 + 31614179 = 31614492

Showing the first eight; more decompositions exist.
