Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520764, here are decompositions:

3 + 31520761 = 31520764
17 + 31520747 = 31520764
137 + 31520627 = 31520764
227 + 31520537 = 31520764
281 + 31520483 = 31520764
311 + 31520453 = 31520764
347 + 31520417 = 31520764
521 + 31520243 = 31520764

Showing the first eight; more decompositions exist.
