Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76644, here are decompositions:

13 + 76631 = 76644
37 + 76607 = 76644
41 + 76603 = 76644
47 + 76597 = 76644
83 + 76561 = 76644
101 + 76543 = 76644
103 + 76541 = 76644
107 + 76537 = 76644

Showing the first eight; more decompositions exist.
