Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664818, here are decompositions:

31 + 8664787 = 8664818
61 + 8664757 = 8664818
79 + 8664739 = 8664818
157 + 8664661 = 8664818
271 + 8664547 = 8664818
367 + 8664451 = 8664818
397 + 8664421 = 8664818
661 + 8664157 = 8664818

Showing the first eight; more decompositions exist.
