Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625330, here are decompositions:

67 + 31625263 = 31625330
151 + 31625179 = 31625330
181 + 31625149 = 31625330
199 + 31625131 = 31625330
271 + 31625059 = 31625330
379 + 31624951 = 31625330
409 + 31624921 = 31625330
523 + 31624807 = 31625330

Showing the first eight; more decompositions exist.
