Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742480, here are decompositions:

11 + 8742469 = 8742480
17 + 8742463 = 8742480
31 + 8742449 = 8742480
59 + 8742421 = 8742480
79 + 8742401 = 8742480
101 + 8742379 = 8742480
113 + 8742367 = 8742480
127 + 8742353 = 8742480

Showing the first eight; more decompositions exist.
