Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577462, here are decompositions:

61 + 31577401 = 31577462
73 + 31577389 = 31577462
79 + 31577383 = 31577462
109 + 31577353 = 31577462
139 + 31577323 = 31577462
193 + 31577269 = 31577462
199 + 31577263 = 31577462
223 + 31577239 = 31577462

Showing the first eight; more decompositions exist.
