Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582632, here are decompositions:

5 + 31582627 = 31582632
19 + 31582613 = 31582632
23 + 31582609 = 31582632
31 + 31582601 = 31582632
43 + 31582589 = 31582632
73 + 31582559 = 31582632
79 + 31582553 = 31582632
101 + 31582531 = 31582632

Showing the first eight; more decompositions exist.
