Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607894, here are decompositions:

37 + 31607857 = 31607894
103 + 31607791 = 31607894
211 + 31607683 = 31607894
223 + 31607671 = 31607894
313 + 31607581 = 31607894
421 + 31607473 = 31607894
433 + 31607461 = 31607894
601 + 31607293 = 31607894

Showing the first eight; more decompositions exist.
