Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161674, here are decompositions:

47 + 161627 = 161674
83 + 161591 = 161674
101 + 161573 = 161674
113 + 161561 = 161674
131 + 161543 = 161674
167 + 161507 = 161674
263 + 161411 = 161674
311 + 161363 = 161674

Showing the first eight; more decompositions exist.
