Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537354, here are decompositions:

41 + 31537313 = 31537354
47 + 31537307 = 31537354
83 + 31537271 = 31537354
131 + 31537223 = 31537354
227 + 31537127 = 31537354
257 + 31537097 = 31537354
311 + 31537043 = 31537354
353 + 31537001 = 31537354

Showing the first eight; more decompositions exist.
