Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690986, here are decompositions:

23 + 8690963 = 8690986
173 + 8690813 = 8690986
197 + 8690789 = 8690986
347 + 8690639 = 8690986
383 + 8690603 = 8690986
419 + 8690567 = 8690986
509 + 8690477 = 8690986
587 + 8690399 = 8690986

Showing the first eight; more decompositions exist.
