Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667940, here are decompositions:

11 + 8667929 = 8667940
41 + 8667899 = 8667940
131 + 8667809 = 8667940
233 + 8667707 = 8667940
251 + 8667689 = 8667940
263 + 8667677 = 8667940
401 + 8667539 = 8667940
419 + 8667521 = 8667940

Showing the first eight; more decompositions exist.
