Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187634, here are decompositions:

3 + 187631 = 187634
37 + 187597 = 187634
61 + 187573 = 187634
103 + 187531 = 187634
127 + 187507 = 187634
157 + 187477 = 187634
163 + 187471 = 187634
193 + 187441 = 187634

Showing the first eight; more decompositions exist.
