Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465552, here are decompositions:

5 + 31465547 = 31465552
23 + 31465529 = 31465552
71 + 31465481 = 31465552
101 + 31465451 = 31465552
263 + 31465289 = 31465552
359 + 31465193 = 31465552
491 + 31465061 = 31465552
743 + 31464809 = 31465552

Showing the first eight; more decompositions exist.
