Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730256, here are decompositions:

107 + 8730149 = 8730256
173 + 8730083 = 8730256
179 + 8730077 = 8730256
257 + 8729999 = 8730256
317 + 8729939 = 8730256
389 + 8729867 = 8730256
419 + 8729837 = 8730256
653 + 8729603 = 8730256

Showing the first eight; more decompositions exist.
