Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465570, here are decompositions:

23 + 31465547 = 31465570
41 + 31465529 = 31465570
89 + 31465481 = 31465570
179 + 31465391 = 31465570
281 + 31465289 = 31465570
347 + 31465223 = 31465570
509 + 31465061 = 31465570
743 + 31464827 = 31465570

Showing the first eight; more decompositions exist.
