Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465524, here are decompositions:

43 + 31465481 = 31465524
73 + 31465451 = 31465524
107 + 31465417 = 31465524
281 + 31465243 = 31465524
331 + 31465193 = 31465524
347 + 31465177 = 31465524
401 + 31465123 = 31465524
463 + 31465061 = 31465524

Showing the first eight; more decompositions exist.
