Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709684, here are decompositions:

7 + 8709677 = 8709684
31 + 8709653 = 8709684
37 + 8709647 = 8709684
73 + 8709611 = 8709684
97 + 8709587 = 8709684
131 + 8709553 = 8709684
157 + 8709527 = 8709684
223 + 8709461 = 8709684

Showing the first eight; more decompositions exist.
