Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464850, here are decompositions:

23 + 31464827 = 31464850
29 + 31464821 = 31464850
41 + 31464809 = 31464850
149 + 31464701 = 31464850
233 + 31464617 = 31464850
269 + 31464581 = 31464850
293 + 31464557 = 31464850
449 + 31464401 = 31464850

Showing the first eight; more decompositions exist.
