Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724152, here are decompositions:

13 + 8724139 = 8724152
79 + 8724073 = 8724152
139 + 8724013 = 8724152
223 + 8723929 = 8724152
331 + 8723821 = 8724152
421 + 8723731 = 8724152
499 + 8723653 = 8724152
601 + 8723551 = 8724152

Showing the first eight; more decompositions exist.
