Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536142, here are decompositions:

41 + 31536101 = 31536142
89 + 31536053 = 31536142
233 + 31535909 = 31536142
263 + 31535879 = 31536142
311 + 31535831 = 31536142
389 + 31535753 = 31536142
401 + 31535741 = 31536142
461 + 31535681 = 31536142

Showing the first eight; more decompositions exist.
