Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460670, here are decompositions:

13 + 31460657 = 31460670
23 + 31460647 = 31460670
61 + 31460609 = 31460670
89 + 31460581 = 31460670
173 + 31460497 = 31460670
179 + 31460491 = 31460670
229 + 31460441 = 31460670
239 + 31460431 = 31460670

Showing the first eight; more decompositions exist.
