Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582612, here are decompositions:

3 + 31582609 = 31582612
11 + 31582601 = 31582612
23 + 31582589 = 31582612
53 + 31582559 = 31582612
59 + 31582553 = 31582612
293 + 31582319 = 31582612
419 + 31582193 = 31582612
449 + 31582163 = 31582612

Showing the first eight; more decompositions exist.
