Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468214, here are decompositions:

3 + 31468211 = 31468214
13 + 31468201 = 31468214
67 + 31468147 = 31468214
277 + 31467937 = 31468214
367 + 31467847 = 31468214
487 + 31467727 = 31468214
523 + 31467691 = 31468214
643 + 31467571 = 31468214

Showing the first eight; more decompositions exist.
