Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661232, here are decompositions:

29 + 8661203 = 8661232
59 + 8661173 = 8661232
71 + 8661161 = 8661232
113 + 8661119 = 8661232
263 + 8660969 = 8661232
311 + 8660921 = 8661232
479 + 8660753 = 8661232
491 + 8660741 = 8661232

Showing the first eight; more decompositions exist.
