Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77612, here are decompositions:

43 + 77569 = 77612
61 + 77551 = 77612
103 + 77509 = 77612
181 + 77431 = 77612
193 + 77419 = 77612
229 + 77383 = 77612
349 + 77263 = 77612
373 + 77239 = 77612

Showing the first eight; more decompositions exist.
