Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76990, here are decompositions:

29 + 76961 = 76990
41 + 76949 = 76990
47 + 76943 = 76990
71 + 76919 = 76990
83 + 76907 = 76990
107 + 76883 = 76990
233 + 76757 = 76990
257 + 76733 = 76990

Showing the first eight; more decompositions exist.
