Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729242, here are decompositions:

3 + 8729239 = 8729242
23 + 8729219 = 8729242
59 + 8729183 = 8729242
101 + 8729141 = 8729242
149 + 8729093 = 8729242
191 + 8729051 = 8729242
359 + 8728883 = 8729242
419 + 8728823 = 8729242

Showing the first eight; more decompositions exist.
