Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187712, here are decompositions:

13 + 187699 = 187712
43 + 187669 = 187712
61 + 187651 = 187712
73 + 187639 = 187712
79 + 187633 = 187712
139 + 187573 = 187712
181 + 187531 = 187712
199 + 187513 = 187712

Showing the first eight; more decompositions exist.
