Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185672, here are decompositions:

31 + 185641 = 185672
73 + 185599 = 185672
79 + 185593 = 185672
103 + 185569 = 185672
139 + 185533 = 185672
181 + 185491 = 185672
271 + 185401 = 185672
313 + 185359 = 185672

Showing the first eight; more decompositions exist.
