Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931618, here are decompositions:

41 + 931577 = 931618
47 + 931571 = 931618
89 + 931529 = 931618
101 + 931517 = 931618
131 + 931487 = 931618
197 + 931421 = 931618
419 + 931199 = 931618
449 + 931169 = 931618

Showing the first eight; more decompositions exist.
