Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465576, here are decompositions:

5 + 31465571 = 31465576
29 + 31465547 = 31465576
47 + 31465529 = 31465576
353 + 31465223 = 31465576
383 + 31465193 = 31465576
1019 + 31464557 = 31465576
1217 + 31464359 = 31465576
1307 + 31464269 = 31465576

Showing the first eight; more decompositions exist.
