Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474894, here are decompositions:

131 + 31474763 = 31474894
173 + 31474721 = 31474894
293 + 31474601 = 31474894
317 + 31474577 = 31474894
461 + 31474433 = 31474894
491 + 31474403 = 31474894
587 + 31474307 = 31474894
593 + 31474301 = 31474894

Showing the first eight; more decompositions exist.
