Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541812, here are decompositions:

13 + 541799 = 541812
31 + 541781 = 541812
41 + 541771 = 541812
53 + 541759 = 541812
101 + 541711 = 541812
113 + 541699 = 541812
151 + 541661 = 541812
181 + 541631 = 541812

Showing the first eight; more decompositions exist.
