Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465222, here are decompositions:

29 + 31465193 = 31465222
281 + 31464941 = 31465222
401 + 31464821 = 31465222
491 + 31464731 = 31465222
521 + 31464701 = 31465222
641 + 31464581 = 31465222
821 + 31464401 = 31465222
863 + 31464359 = 31465222

Showing the first eight; more decompositions exist.
