Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619242, here are decompositions:

13 + 8619229 = 8619242
19 + 8619223 = 8619242
31 + 8619211 = 8619242
43 + 8619199 = 8619242
211 + 8619031 = 8619242
283 + 8618959 = 8619242
349 + 8618893 = 8619242
409 + 8618833 = 8619242

Showing the first eight; more decompositions exist.
