Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607738, here are decompositions:

67 + 31607671 = 31607738
109 + 31607629 = 31607738
139 + 31607599 = 31607738
157 + 31607581 = 31607738
277 + 31607461 = 31607738
397 + 31607341 = 31607738
439 + 31607299 = 31607738
457 + 31607281 = 31607738

Showing the first eight; more decompositions exist.
