Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152812, here are decompositions:

3 + 152809 = 152812
29 + 152783 = 152812
59 + 152753 = 152812
83 + 152729 = 152812
89 + 152723 = 152812
131 + 152681 = 152812
173 + 152639 = 152812
281 + 152531 = 152812

Showing the first eight; more decompositions exist.
