Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500764, here are decompositions:

73 + 31500691 = 31500764
277 + 31500487 = 31500764
307 + 31500457 = 31500764
313 + 31500451 = 31500764
397 + 31500367 = 31500764
571 + 31500193 = 31500764
577 + 31500187 = 31500764
1033 + 31499731 = 31500764

Showing the first eight; more decompositions exist.
