Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607932, here are decompositions:

11 + 31607921 = 31607932
23 + 31607909 = 31607932
29 + 31607903 = 31607932
101 + 31607831 = 31607932
149 + 31607783 = 31607932
353 + 31607579 = 31607932
401 + 31607531 = 31607932
443 + 31607489 = 31607932

Showing the first eight; more decompositions exist.
