Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607452, here are decompositions:

3 + 31607449 = 31607452
5 + 31607447 = 31607452
29 + 31607423 = 31607452
53 + 31607399 = 31607452
89 + 31607363 = 31607452
251 + 31607201 = 31607452
479 + 31606973 = 31607452
509 + 31606943 = 31607452

Showing the first eight; more decompositions exist.
