Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724488, here are decompositions:

67 + 8724421 = 8724488
229 + 8724259 = 8724488
307 + 8724181 = 8724488
349 + 8724139 = 8724488
541 + 8723947 = 8724488
601 + 8723887 = 8724488
757 + 8723731 = 8724488
811 + 8723677 = 8724488

Showing the first eight; more decompositions exist.
