Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724122, here are decompositions:

109 + 8724013 = 8724122
193 + 8723929 = 8724122
223 + 8723899 = 8724122
229 + 8723893 = 8724122
271 + 8723851 = 8724122
571 + 8723551 = 8724122
601 + 8723521 = 8724122
643 + 8723479 = 8724122

Showing the first eight; more decompositions exist.
