Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556762, here are decompositions:

109 + 31556653 = 31556762
283 + 31556479 = 31556762
373 + 31556389 = 31556762
409 + 31556353 = 31556762
421 + 31556341 = 31556762
439 + 31556323 = 31556762
613 + 31556149 = 31556762
619 + 31556143 = 31556762

Showing the first eight; more decompositions exist.
