Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625270, here are decompositions:

7 + 31625263 = 31625270
139 + 31625131 = 31625270
211 + 31625059 = 31625270
331 + 31624939 = 31625270
349 + 31624921 = 31625270
409 + 31624861 = 31625270
421 + 31624849 = 31625270
433 + 31624837 = 31625270

Showing the first eight; more decompositions exist.
