Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625044, here are decompositions:

5 + 31625039 = 31625044
137 + 31624907 = 31625044
263 + 31624781 = 31625044
281 + 31624763 = 31625044
383 + 31624661 = 31625044
401 + 31624643 = 31625044
431 + 31624613 = 31625044
587 + 31624457 = 31625044

Showing the first eight; more decompositions exist.
