Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607774, here are decompositions:

103 + 31607671 = 31607774
193 + 31607581 = 31607774
223 + 31607551 = 31607774
271 + 31607503 = 31607774
313 + 31607461 = 31607774
433 + 31607341 = 31607774
547 + 31607227 = 31607774
673 + 31607101 = 31607774

Showing the first eight; more decompositions exist.
