Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707228, here are decompositions:

137 + 8707091 = 8707228
191 + 8707037 = 8707228
197 + 8707031 = 8707228
281 + 8706947 = 8707228
347 + 8706881 = 8707228
359 + 8706869 = 8707228
521 + 8706707 = 8707228
557 + 8706671 = 8707228

Showing the first eight; more decompositions exist.
