Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619964, here are decompositions:

71 + 8619893 = 8619964
107 + 8619857 = 8619964
167 + 8619797 = 8619964
173 + 8619791 = 8619964
191 + 8619773 = 8619964
251 + 8619713 = 8619964
281 + 8619683 = 8619964
491 + 8619473 = 8619964

Showing the first eight; more decompositions exist.
