Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607954, here are decompositions:

97 + 31607857 = 31607954
163 + 31607791 = 31607954
271 + 31607683 = 31607954
283 + 31607671 = 31607954
373 + 31607581 = 31607954
613 + 31607341 = 31607954
661 + 31607293 = 31607954
673 + 31607281 = 31607954

Showing the first eight; more decompositions exist.
