Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690490, here are decompositions:

13 + 8690477 = 8690490
37 + 8690453 = 8690490
79 + 8690411 = 8690490
103 + 8690387 = 8690490
113 + 8690377 = 8690490
131 + 8690359 = 8690490
139 + 8690351 = 8690490
157 + 8690333 = 8690490

Showing the first eight; more decompositions exist.
