Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730280, here are decompositions:

11 + 8730269 = 8730280
17 + 8730263 = 8730280
23 + 8730257 = 8730280
131 + 8730149 = 8730280
197 + 8730083 = 8730280
281 + 8729999 = 8730280
431 + 8729849 = 8730280
443 + 8729837 = 8730280

Showing the first eight; more decompositions exist.
