Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464922, here are decompositions:

101 + 31464821 = 31464922
113 + 31464809 = 31464922
191 + 31464731 = 31464922
479 + 31464443 = 31464922
521 + 31464401 = 31464922
563 + 31464359 = 31464922
641 + 31464281 = 31464922
653 + 31464269 = 31464922

Showing the first eight; more decompositions exist.
