Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625602, here are decompositions:

3 + 31625599 = 31625602
23 + 31625579 = 31625602
149 + 31625453 = 31625602
191 + 31625411 = 31625602
251 + 31625351 = 31625602
563 + 31625039 = 31625602
773 + 31624829 = 31625602
821 + 31624781 = 31625602

Showing the first eight; more decompositions exist.
