Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625758, here are decompositions:

5 + 31625753 = 31625758
107 + 31625651 = 31625758
179 + 31625579 = 31625758
191 + 31625567 = 31625758
251 + 31625507 = 31625758
347 + 31625411 = 31625758
701 + 31625057 = 31625758
719 + 31625039 = 31625758

Showing the first eight; more decompositions exist.
