Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536832, here are decompositions:

3 + 31536829 = 31536832
11 + 31536821 = 31536832
59 + 31536773 = 31536832
101 + 31536731 = 31536832
113 + 31536719 = 31536832
281 + 31536551 = 31536832
293 + 31536539 = 31536832
311 + 31536521 = 31536832

Showing the first eight; more decompositions exist.
