Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742466, here are decompositions:

3 + 8742463 = 8742466
17 + 8742449 = 8742466
107 + 8742359 = 8742466
113 + 8742353 = 8742466
149 + 8742317 = 8742466
269 + 8742197 = 8742466
389 + 8742077 = 8742466
479 + 8741987 = 8742466

Showing the first eight; more decompositions exist.
