Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504604, here are decompositions:

13 + 31504591 = 31504604
31 + 31504573 = 31504604
37 + 31504567 = 31504604
151 + 31504453 = 31504604
277 + 31504327 = 31504604
421 + 31504183 = 31504604
631 + 31503973 = 31504604
643 + 31503961 = 31504604

Showing the first eight; more decompositions exist.
