Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625582, here are decompositions:

3 + 31625579 = 31625582
19 + 31625563 = 31625582
73 + 31625509 = 31625582
151 + 31625431 = 31625582
181 + 31625401 = 31625582
199 + 31625383 = 31625582
433 + 31625149 = 31625582
523 + 31625059 = 31625582

Showing the first eight; more decompositions exist.
