Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464946, here are decompositions:

5 + 31464941 = 31464946
137 + 31464809 = 31464946
389 + 31464557 = 31464946
503 + 31464443 = 31464946
587 + 31464359 = 31464946
677 + 31464269 = 31464946
797 + 31464149 = 31464946
809 + 31464137 = 31464946

Showing the first eight; more decompositions exist.
