Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726858, here are decompositions:

97 + 8726761 = 8726858
181 + 8726677 = 8726858
211 + 8726647 = 8726858
271 + 8726587 = 8726858
331 + 8726527 = 8726858
337 + 8726521 = 8726858
379 + 8726479 = 8726858
397 + 8726461 = 8726858

Showing the first eight; more decompositions exist.
