Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678264, here are decompositions:

61 + 8678203 = 8678264
103 + 8678161 = 8678264
151 + 8678113 = 8678264
181 + 8678083 = 8678264
211 + 8678053 = 8678264
271 + 8677993 = 8678264
313 + 8677951 = 8678264
373 + 8677891 = 8678264

Showing the first eight; more decompositions exist.
