Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607152, here are decompositions:

113 + 31607039 = 31607152
173 + 31606979 = 31607152
179 + 31606973 = 31607152
233 + 31606919 = 31607152
449 + 31606703 = 31607152
461 + 31606691 = 31607152
491 + 31606661 = 31607152
509 + 31606643 = 31607152

Showing the first eight; more decompositions exist.
