Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719258, here are decompositions:

5 + 8719253 = 8719258
47 + 8719211 = 8719258
59 + 8719199 = 8719258
71 + 8719187 = 8719258
131 + 8719127 = 8719258
227 + 8719031 = 8719258
389 + 8718869 = 8719258
419 + 8718839 = 8719258

Showing the first eight; more decompositions exist.
