Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700742, here are decompositions:

179 + 8700563 = 8700742
269 + 8700473 = 8700742
293 + 8700449 = 8700742
311 + 8700431 = 8700742
359 + 8700383 = 8700742
389 + 8700353 = 8700742
443 + 8700299 = 8700742
461 + 8700281 = 8700742

Showing the first eight; more decompositions exist.
