Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465534, here are decompositions:

5 + 31465529 = 31465534
53 + 31465481 = 31465534
83 + 31465451 = 31465534
311 + 31465223 = 31465534
587 + 31464947 = 31465534
593 + 31464941 = 31465534
953 + 31464581 = 31465534
977 + 31464557 = 31465534

Showing the first eight; more decompositions exist.
