Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607654, here are decompositions:

73 + 31607581 = 31607654
103 + 31607551 = 31607654
151 + 31607503 = 31607654
181 + 31607473 = 31607654
193 + 31607461 = 31607654
313 + 31607341 = 31607654
373 + 31607281 = 31607654
607 + 31607047 = 31607654

Showing the first eight; more decompositions exist.
