Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719090, here are decompositions:

41 + 8719049 = 8719090
53 + 8719037 = 8719090
59 + 8719031 = 8719090
137 + 8718953 = 8719090
173 + 8718917 = 8719090
239 + 8718851 = 8719090
251 + 8718839 = 8719090
257 + 8718833 = 8719090

Showing the first eight; more decompositions exist.
