Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77038, here are decompositions:

47 + 76991 = 77038
89 + 76949 = 77038
131 + 76907 = 77038
167 + 76871 = 77038
191 + 76847 = 77038
257 + 76781 = 77038
281 + 76757 = 77038
359 + 76679 = 77038

Showing the first eight; more decompositions exist.
