Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167642, here are decompositions:

19 + 167623 = 167642
31 + 167611 = 167642
151 + 167491 = 167642
193 + 167449 = 167642
199 + 167443 = 167642
229 + 167413 = 167642
313 + 167329 = 167642
331 + 167311 = 167642

Showing the first eight; more decompositions exist.
