Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731066, here are decompositions:

83 + 8730983 = 8731066
89 + 8730977 = 8731066
137 + 8730929 = 8731066
173 + 8730893 = 8731066
263 + 8730803 = 8731066
269 + 8730797 = 8731066
593 + 8730473 = 8731066
599 + 8730467 = 8731066

Showing the first eight; more decompositions exist.
