Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625716, here are decompositions:

113 + 31625603 = 31625716
137 + 31625579 = 31625716
149 + 31625567 = 31625716
179 + 31625537 = 31625716
263 + 31625453 = 31625716
569 + 31625147 = 31625716
659 + 31625057 = 31625716
677 + 31625039 = 31625716

Showing the first eight; more decompositions exist.
