Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730218, here are decompositions:

37 + 8730181 = 8730218
61 + 8730157 = 8730218
67 + 8730151 = 8730218
127 + 8730091 = 8730218
151 + 8730067 = 8730218
241 + 8729977 = 8730218
331 + 8729887 = 8730218
337 + 8729881 = 8730218

Showing the first eight; more decompositions exist.
