Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454662, here are decompositions:

11 + 31454651 = 31454662
149 + 31454513 = 31454662
179 + 31454483 = 31454662
311 + 31454351 = 31454662
443 + 31454219 = 31454662
461 + 31454201 = 31454662
719 + 31453943 = 31454662
821 + 31453841 = 31454662

Showing the first eight; more decompositions exist.
