Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724258, here are decompositions:

5 + 8724253 = 8724258
17 + 8724241 = 8724258
89 + 8724169 = 8724258
97 + 8724161 = 8724258
131 + 8724127 = 8724258
157 + 8724101 = 8724258
271 + 8723987 = 8724258
281 + 8723977 = 8724258

Showing the first eight; more decompositions exist.
