Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625236, here are decompositions:

89 + 31625147 = 31625236
179 + 31625057 = 31625236
197 + 31625039 = 31625236
257 + 31624979 = 31625236
563 + 31624673 = 31625236
593 + 31624643 = 31625236
677 + 31624559 = 31625236
887 + 31624349 = 31625236

Showing the first eight; more decompositions exist.
