Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729490, here are decompositions:

23 + 8729467 = 8729490
61 + 8729429 = 8729490
79 + 8729411 = 8729490
89 + 8729401 = 8729490
101 + 8729389 = 8729490
157 + 8729333 = 8729490
163 + 8729327 = 8729490
167 + 8729323 = 8729490

Showing the first eight; more decompositions exist.
