Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740386, here are decompositions:

13 + 8740373 = 8740386
19 + 8740367 = 8740386
59 + 8740327 = 8740386
97 + 8740289 = 8740386
113 + 8740273 = 8740386
167 + 8740219 = 8740386
199 + 8740187 = 8740386
223 + 8740163 = 8740386

Showing the first eight; more decompositions exist.
