Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701390, here are decompositions:

23 + 8701367 = 8701390
41 + 8701349 = 8701390
101 + 8701289 = 8701390
179 + 8701211 = 8701390
197 + 8701193 = 8701390
227 + 8701163 = 8701390
389 + 8701001 = 8701390
443 + 8700947 = 8701390

Showing the first eight; more decompositions exist.
