Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742502, here are decompositions:

3 + 8742499 = 8742502
5 + 8742497 = 8742502
53 + 8742449 = 8742502
101 + 8742401 = 8742502
149 + 8742353 = 8742502
239 + 8742263 = 8742502
443 + 8742059 = 8742502
491 + 8742011 = 8742502

Showing the first eight; more decompositions exist.
