Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057218, here are decompositions:

37 + 1057181 = 1057218
61 + 1057157 = 1057218
89 + 1057129 = 1057218
101 + 1057117 = 1057218
131 + 1057087 = 1057218
167 + 1057051 = 1057218
181 + 1057037 = 1057218
199 + 1057019 = 1057218

Showing the first eight; more decompositions exist.
