Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707486, here are decompositions:

107 + 8707379 = 8707486
197 + 8707289 = 8707486
383 + 8707103 = 8707486
449 + 8707037 = 8707486
479 + 8707007 = 8707486
503 + 8706983 = 8707486
617 + 8706869 = 8707486
653 + 8706833 = 8707486

Showing the first eight; more decompositions exist.
