Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590632, here are decompositions:

43 + 31590589 = 31590632
61 + 31590571 = 31590632
163 + 31590469 = 31590632
181 + 31590451 = 31590632
211 + 31590421 = 31590632
421 + 31590211 = 31590632
499 + 31590133 = 31590632
571 + 31590061 = 31590632

Showing the first eight; more decompositions exist.
