Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531764, here are decompositions:

13 + 31531751 = 31531764
37 + 31531727 = 31531764
97 + 31531667 = 31531764
137 + 31531627 = 31531764
241 + 31531523 = 31531764
281 + 31531483 = 31531764
293 + 31531471 = 31531764
307 + 31531457 = 31531764

Showing the first eight; more decompositions exist.
