Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629406, here are decompositions:

73 + 8629333 = 8629406
109 + 8629297 = 8629406
127 + 8629279 = 8629406
193 + 8629213 = 8629406
283 + 8629123 = 8629406
397 + 8629009 = 8629406
433 + 8628973 = 8629406
439 + 8628967 = 8629406

Showing the first eight; more decompositions exist.
