Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187718, here are decompositions:

7 + 187711 = 187718
19 + 187699 = 187718
31 + 187687 = 187718
67 + 187651 = 187718
79 + 187639 = 187718
211 + 187507 = 187718
241 + 187477 = 187718
277 + 187441 = 187718

Showing the first eight; more decompositions exist.
