Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743630, here are decompositions:

41 + 8743589 = 8743630
47 + 8743583 = 8743630
59 + 8743571 = 8743630
83 + 8743547 = 8743630
131 + 8743499 = 8743630
251 + 8743379 = 8743630
263 + 8743367 = 8743630
281 + 8743349 = 8743630

Showing the first eight; more decompositions exist.
