Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452214, here are decompositions:

5 + 31452209 = 31452214
11 + 31452203 = 31452214
41 + 31452173 = 31452214
83 + 31452131 = 31452214
173 + 31452041 = 31452214
461 + 31451753 = 31452214
491 + 31451723 = 31452214
503 + 31451711 = 31452214

Showing the first eight; more decompositions exist.
