Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625214, here are decompositions:

67 + 31625147 = 31625214
83 + 31625131 = 31625214
157 + 31625057 = 31625214
263 + 31624951 = 31625214
293 + 31624921 = 31625214
307 + 31624907 = 31625214
353 + 31624861 = 31625214
431 + 31624783 = 31625214

Showing the first eight; more decompositions exist.
