Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742730, here are decompositions:

41 + 8742689 = 8742730
53 + 8742677 = 8742730
107 + 8742623 = 8742730
179 + 8742551 = 8742730
233 + 8742497 = 8742730
281 + 8742449 = 8742730
383 + 8742347 = 8742730
467 + 8742263 = 8742730

Showing the first eight; more decompositions exist.
