Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724182, here are decompositions:

13 + 8724169 = 8724182
43 + 8724139 = 8724182
109 + 8724073 = 8724182
283 + 8723899 = 8724182
331 + 8723851 = 8724182
349 + 8723833 = 8724182
613 + 8723569 = 8724182
631 + 8723551 = 8724182

Showing the first eight; more decompositions exist.
