Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620042, here are decompositions:

149 + 8619893 = 8620042
173 + 8619869 = 8620042
251 + 8619791 = 8620042
269 + 8619773 = 8620042
359 + 8619683 = 8620042
419 + 8619623 = 8620042
449 + 8619593 = 8620042
491 + 8619551 = 8620042

Showing the first eight; more decompositions exist.
