Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187672, here are decompositions:

3 + 187669 = 187672
11 + 187661 = 187672
41 + 187631 = 187672
113 + 187559 = 187672
239 + 187433 = 187672
263 + 187409 = 187672
293 + 187379 = 187672
311 + 187361 = 187672

Showing the first eight; more decompositions exist.
