Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639534, here are decompositions:

3 + 8639531 = 8639534
73 + 8639461 = 8639534
271 + 8639263 = 8639534
283 + 8639251 = 8639534
307 + 8639227 = 8639534
373 + 8639161 = 8639534
523 + 8639011 = 8639534
601 + 8638933 = 8639534

Showing the first eight; more decompositions exist.
