Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690512, here are decompositions:

23 + 8690489 = 8690512
59 + 8690453 = 8690512
101 + 8690411 = 8690512
113 + 8690399 = 8690512
179 + 8690333 = 8690512
419 + 8690093 = 8690512
443 + 8690069 = 8690512
449 + 8690063 = 8690512

Showing the first eight; more decompositions exist.
