Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37978, here are decompositions:

11 + 37967 = 37978
71 + 37907 = 37978
89 + 37889 = 37978
107 + 37871 = 37978
131 + 37847 = 37978
167 + 37811 = 37978
179 + 37799 = 37978
197 + 37781 = 37978

Showing the first eight; more decompositions exist.
