Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632578, here are decompositions:

5 + 8632573 = 8632578
47 + 8632531 = 8632578
89 + 8632489 = 8632578
127 + 8632451 = 8632578
167 + 8632411 = 8632578
179 + 8632399 = 8632578
191 + 8632387 = 8632578
197 + 8632381 = 8632578

Showing the first eight; more decompositions exist.
