Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187814, here are decompositions:

103 + 187711 = 187814
127 + 187687 = 187814
163 + 187651 = 187814
181 + 187633 = 187814
241 + 187573 = 187814
283 + 187531 = 187814
307 + 187507 = 187814
337 + 187477 = 187814

Showing the first eight; more decompositions exist.
