Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742488, here are decompositions:

19 + 8742469 = 8742488
67 + 8742421 = 8742488
109 + 8742379 = 8742488
229 + 8742259 = 8742488
331 + 8742157 = 8742488
367 + 8742121 = 8742488
421 + 8742067 = 8742488
499 + 8741989 = 8742488

Showing the first eight; more decompositions exist.
