Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615428, here are decompositions:

5 + 8615423 = 8615428
149 + 8615279 = 8615428
167 + 8615261 = 8615428
191 + 8615237 = 8615428
197 + 8615231 = 8615428
251 + 8615177 = 8615428
449 + 8614979 = 8615428
461 + 8614967 = 8615428

Showing the first eight; more decompositions exist.
