Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536892, here are decompositions:

29 + 31536863 = 31536892
71 + 31536821 = 31536892
173 + 31536719 = 31536892
263 + 31536629 = 31536892
353 + 31536539 = 31536892
509 + 31536383 = 31536892
599 + 31536293 = 31536892
839 + 31536053 = 31536892

Showing the first eight; more decompositions exist.
