Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484774, here are decompositions:

3 + 31484771 = 31484774
127 + 31484647 = 31484774
157 + 31484617 = 31484774
241 + 31484533 = 31484774
271 + 31484503 = 31484774
313 + 31484461 = 31484774
397 + 31484377 = 31484774
421 + 31484353 = 31484774

Showing the first eight; more decompositions exist.
