Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641982, here are decompositions:

73 + 8641909 = 8641982
109 + 8641873 = 8641982
163 + 8641819 = 8641982
199 + 8641783 = 8641982
241 + 8641741 = 8641982
313 + 8641669 = 8641982
331 + 8641651 = 8641982
379 + 8641603 = 8641982

Showing the first eight; more decompositions exist.
