Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76646, here are decompositions:

43 + 76603 = 76646
67 + 76579 = 76646
103 + 76543 = 76646
109 + 76537 = 76646
127 + 76519 = 76646
139 + 76507 = 76646
223 + 76423 = 76646
277 + 76369 = 76646

Showing the first eight; more decompositions exist.
