Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176840, here are decompositions:

31 + 176809 = 176840
43 + 176797 = 176840
61 + 176779 = 176840
127 + 176713 = 176840
163 + 176677 = 176840
199 + 176641 = 176840
211 + 176629 = 176840
229 + 176611 = 176840

Showing the first eight; more decompositions exist.
