Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607842, here are decompositions:

3 + 31607839 = 31607842
11 + 31607831 = 31607842
53 + 31607789 = 31607842
59 + 31607783 = 31607842
263 + 31607579 = 31607842
311 + 31607531 = 31607842
353 + 31607489 = 31607842
419 + 31607423 = 31607842

Showing the first eight; more decompositions exist.
