Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625756, here are decompositions:

3 + 31625753 = 31625756
103 + 31625653 = 31625756
109 + 31625647 = 31625756
139 + 31625617 = 31625756
157 + 31625599 = 31625756
193 + 31625563 = 31625756
373 + 31625383 = 31625756
577 + 31625179 = 31625756

Showing the first eight; more decompositions exist.
