Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72812, here are decompositions:

73 + 72739 = 72812
79 + 72733 = 72812
139 + 72673 = 72812
151 + 72661 = 72812
163 + 72649 = 72812
199 + 72613 = 72812
331 + 72481 = 72812
433 + 72379 = 72812

Showing the first eight; more decompositions exist.
