Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690812, here are decompositions:

23 + 8690789 = 8690812
29 + 8690783 = 8690812
71 + 8690741 = 8690812
149 + 8690663 = 8690812
173 + 8690639 = 8690812
281 + 8690531 = 8690812
359 + 8690453 = 8690812
401 + 8690411 = 8690812

Showing the first eight; more decompositions exist.
