Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730144, here are decompositions:

41 + 8730103 = 8730144
53 + 8730091 = 8730144
61 + 8730083 = 8730144
67 + 8730077 = 8730144
131 + 8730013 = 8730144
167 + 8729977 = 8730144
257 + 8729887 = 8730144
263 + 8729881 = 8730144

Showing the first eight; more decompositions exist.
