Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724230, here are decompositions:

7 + 8724223 = 8724230
61 + 8724169 = 8724230
103 + 8724127 = 8724230
157 + 8724073 = 8724230
283 + 8723947 = 8724230
331 + 8723899 = 8724230
337 + 8723893 = 8724230
379 + 8723851 = 8724230

Showing the first eight; more decompositions exist.
