Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622782, here are decompositions:

19 + 8622763 = 8622782
61 + 8622721 = 8622782
271 + 8622511 = 8622782
283 + 8622499 = 8622782
313 + 8622469 = 8622782
409 + 8622373 = 8622782
439 + 8622343 = 8622782
541 + 8622241 = 8622782

Showing the first eight; more decompositions exist.
