Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690492, here are decompositions:

3 + 8690489 = 8690492
79 + 8690413 = 8690492
199 + 8690293 = 8690492
271 + 8690221 = 8690492
373 + 8690119 = 8690492
523 + 8689969 = 8690492
739 + 8689753 = 8690492
883 + 8689609 = 8690492

Showing the first eight; more decompositions exist.
