Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536124, here are decompositions:

23 + 31536101 = 31536124
71 + 31536053 = 31536124
107 + 31536017 = 31536124
293 + 31535831 = 31536124
383 + 31535741 = 31536124
443 + 31535681 = 31536124
467 + 31535657 = 31536124
491 + 31535633 = 31536124

Showing the first eight; more decompositions exist.
