Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724146, here are decompositions:

3 + 8724143 = 8724146
7 + 8724139 = 8724146
19 + 8724127 = 8724146
73 + 8724073 = 8724146
199 + 8723947 = 8724146
313 + 8723833 = 8724146
439 + 8723707 = 8724146
577 + 8723569 = 8724146

Showing the first eight; more decompositions exist.
