Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513670, here are decompositions:

3 + 31513667 = 31513670
109 + 31513561 = 31513670
337 + 31513333 = 31513670
367 + 31513303 = 31513670
457 + 31513213 = 31513670
523 + 31513147 = 31513670
547 + 31513123 = 31513670
607 + 31513063 = 31513670

Showing the first eight; more decompositions exist.
