Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175816, here are decompositions:

5 + 175811 = 175816
59 + 175757 = 175816
89 + 175727 = 175816
107 + 175709 = 175816
167 + 175649 = 175816
293 + 175523 = 175816
317 + 175499 = 175816
353 + 175463 = 175816

Showing the first eight; more decompositions exist.
