Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690624, here are decompositions:

13 + 8690611 = 8690624
31 + 8690593 = 8690624
67 + 8690557 = 8690624
73 + 8690551 = 8690624
211 + 8690413 = 8690624
307 + 8690317 = 8690624
331 + 8690293 = 8690624
421 + 8690203 = 8690624

Showing the first eight; more decompositions exist.
