Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622812, here are decompositions:

19 + 8622793 = 8622812
31 + 8622781 = 8622812
283 + 8622529 = 8622812
313 + 8622499 = 8622812
349 + 8622463 = 8622812
421 + 8622391 = 8622812
433 + 8622379 = 8622812
439 + 8622373 = 8622812

Showing the first eight; more decompositions exist.
