Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465492, here are decompositions:

11 + 31465481 = 31465492
41 + 31465451 = 31465492
101 + 31465391 = 31465492
269 + 31465223 = 31465492
431 + 31465061 = 31465492
683 + 31464809 = 31465492
761 + 31464731 = 31465492
911 + 31464581 = 31465492

Showing the first eight; more decompositions exist.
