Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474798, here are decompositions:

107 + 31474691 = 31474798
197 + 31474601 = 31474798
227 + 31474571 = 31474798
239 + 31474559 = 31474798
317 + 31474481 = 31474798
401 + 31474397 = 31474798
479 + 31474319 = 31474798
491 + 31474307 = 31474798

Showing the first eight; more decompositions exist.
