Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668802, here are decompositions:

3 + 8668799 = 8668802
19 + 8668783 = 8668802
61 + 8668741 = 8668802
193 + 8668609 = 8668802
283 + 8668519 = 8668802
313 + 8668489 = 8668802
379 + 8668423 = 8668802
421 + 8668381 = 8668802

Showing the first eight; more decompositions exist.
