Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641412, here are decompositions:

61 + 8641351 = 8641412
103 + 8641309 = 8641412
139 + 8641273 = 8641412
163 + 8641249 = 8641412
181 + 8641231 = 8641412
349 + 8641063 = 8641412
463 + 8640949 = 8641412
523 + 8640889 = 8641412

Showing the first eight; more decompositions exist.
