Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740390, here are decompositions:

3 + 8740387 = 8740390
17 + 8740373 = 8740390
23 + 8740367 = 8740390
53 + 8740337 = 8740390
59 + 8740331 = 8740390
89 + 8740301 = 8740390
101 + 8740289 = 8740390
227 + 8740163 = 8740390

Showing the first eight; more decompositions exist.
