Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619764, here are decompositions:

103 + 8619661 = 8619764
163 + 8619601 = 8619764
331 + 8619433 = 8619764
337 + 8619427 = 8619764
367 + 8619397 = 8619764
421 + 8619343 = 8619764
523 + 8619241 = 8619764
541 + 8619223 = 8619764

Showing the first eight; more decompositions exist.
