Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740086, here are decompositions:

83 + 8740003 = 8740086
149 + 8739937 = 8740086
167 + 8739919 = 8740086
263 + 8739823 = 8740086
283 + 8739803 = 8740086
317 + 8739769 = 8740086
337 + 8739749 = 8740086
347 + 8739739 = 8740086

Showing the first eight; more decompositions exist.
