Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749166, here are decompositions:

3 + 8749163 = 8749166
79 + 8749087 = 8749166
193 + 8748973 = 8749166
277 + 8748889 = 8749166
313 + 8748853 = 8749166
379 + 8748787 = 8749166
457 + 8748709 = 8749166
523 + 8748643 = 8749166

Showing the first eight; more decompositions exist.
