Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690722, here are decompositions:

59 + 8690663 = 8690722
83 + 8690639 = 8690722
191 + 8690531 = 8690722
233 + 8690489 = 8690722
269 + 8690453 = 8690722
311 + 8690411 = 8690722
389 + 8690333 = 8690722
419 + 8690303 = 8690722

Showing the first eight; more decompositions exist.
