Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690448, here are decompositions:

37 + 8690411 = 8690448
61 + 8690387 = 8690448
71 + 8690377 = 8690448
89 + 8690359 = 8690448
97 + 8690351 = 8690448
131 + 8690317 = 8690448
157 + 8690291 = 8690448
181 + 8690267 = 8690448

Showing the first eight; more decompositions exist.
