Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724470, here are decompositions:

3 + 8724467 = 8724470
151 + 8724319 = 8724470
211 + 8724259 = 8724470
229 + 8724241 = 8724470
331 + 8724139 = 8724470
397 + 8724073 = 8724470
457 + 8724013 = 8724470
523 + 8723947 = 8724470

Showing the first eight; more decompositions exist.
