Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576670, here are decompositions:

31 + 31576639 = 31576670
193 + 31576477 = 31576670
211 + 31576459 = 31576670
409 + 31576261 = 31576670
439 + 31576231 = 31576670
661 + 31576009 = 31576670
733 + 31575937 = 31576670
877 + 31575793 = 31576670

Showing the first eight; more decompositions exist.
