Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625088, here are decompositions:

29 + 31625059 = 31625088
31 + 31625057 = 31625088
109 + 31624979 = 31625088
137 + 31624951 = 31625088
149 + 31624939 = 31625088
167 + 31624921 = 31625088
181 + 31624907 = 31625088
227 + 31624861 = 31625088

Showing the first eight; more decompositions exist.
