Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582692, here are decompositions:

13 + 31582679 = 31582692
19 + 31582673 = 31582692
59 + 31582633 = 31582692
61 + 31582631 = 31582692
79 + 31582613 = 31582692
83 + 31582609 = 31582692
103 + 31582589 = 31582692
139 + 31582553 = 31582692

Showing the first eight; more decompositions exist.
