Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137672, here are decompositions:

13 + 137659 = 137672
19 + 137653 = 137672
79 + 137593 = 137672
181 + 137491 = 137672
229 + 137443 = 137672
313 + 137359 = 137672
331 + 137341 = 137672
421 + 137251 = 137672

Showing the first eight; more decompositions exist.
