Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76688, here are decompositions:

37 + 76651 = 76688
109 + 76579 = 76688
127 + 76561 = 76688
151 + 76537 = 76688
181 + 76507 = 76688
439 + 76249 = 76688
457 + 76231 = 76688
541 + 76147 = 76688

Showing the first eight; more decompositions exist.
