Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537466, here are decompositions:

127 + 31537339 = 31537466
139 + 31537327 = 31537466
157 + 31537309 = 31537466
193 + 31537273 = 31537466
199 + 31537267 = 31537466
223 + 31537243 = 31537466
313 + 31537153 = 31537466
379 + 31537087 = 31537466

Showing the first eight; more decompositions exist.
