Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742028, here are decompositions:

17 + 8742011 = 8742028
41 + 8741987 = 8742028
167 + 8741861 = 8742028
227 + 8741801 = 8742028
389 + 8741639 = 8742028
419 + 8741609 = 8742028
557 + 8741471 = 8742028
569 + 8741459 = 8742028

Showing the first eight; more decompositions exist.
