Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187646, here are decompositions:

7 + 187639 = 187646
13 + 187633 = 187646
73 + 187573 = 187646
139 + 187507 = 187646
223 + 187423 = 187646
229 + 187417 = 187646
307 + 187339 = 187646
373 + 187273 = 187646

Showing the first eight; more decompositions exist.
