Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740222, here are decompositions:

3 + 8740219 = 8740222
53 + 8740169 = 8740222
59 + 8740163 = 8740222
83 + 8740139 = 8740222
269 + 8739953 = 8740222
311 + 8739911 = 8740222
353 + 8739869 = 8740222
401 + 8739821 = 8740222

Showing the first eight; more decompositions exist.
