Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641124, here are decompositions:

31 + 8641093 = 8641124
61 + 8641063 = 8641124
157 + 8640967 = 8641124
241 + 8640883 = 8641124
307 + 8640817 = 8641124
337 + 8640787 = 8641124
421 + 8640703 = 8641124
433 + 8640691 = 8641124

Showing the first eight; more decompositions exist.
