Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173812, here are decompositions:

5 + 173807 = 173812
29 + 173783 = 173812
71 + 173741 = 173812
83 + 173729 = 173812
113 + 173699 = 173812
239 + 173573 = 173812
251 + 173561 = 173812
263 + 173549 = 173812

Showing the first eight; more decompositions exist.
