Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74818, here are decompositions:

47 + 74771 = 74818
59 + 74759 = 74818
71 + 74747 = 74818
89 + 74729 = 74818
101 + 74717 = 74818
131 + 74687 = 74818
251 + 74567 = 74818
257 + 74561 = 74818

Showing the first eight; more decompositions exist.
