Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690908, here are decompositions:

41 + 8690867 = 8690908
167 + 8690741 = 8690908
269 + 8690639 = 8690908
419 + 8690489 = 8690908
431 + 8690477 = 8690908
509 + 8690399 = 8690908
521 + 8690387 = 8690908
557 + 8690351 = 8690908

Showing the first eight; more decompositions exist.
