Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707240, here are decompositions:

137 + 8707103 = 8707240
149 + 8707091 = 8707240
233 + 8707007 = 8707240
257 + 8706983 = 8707240
293 + 8706947 = 8707240
359 + 8706881 = 8707240
449 + 8706791 = 8707240
569 + 8706671 = 8707240

Showing the first eight; more decompositions exist.
