Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465000, here are decompositions:

53 + 31464947 = 31465000
59 + 31464941 = 31465000
173 + 31464827 = 31465000
179 + 31464821 = 31465000
191 + 31464809 = 31465000
269 + 31464731 = 31465000
383 + 31464617 = 31465000
419 + 31464581 = 31465000

Showing the first eight; more decompositions exist.
