Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577426, here are decompositions:

37 + 31577389 = 31577426
43 + 31577383 = 31577426
73 + 31577353 = 31577426
103 + 31577323 = 31577426
157 + 31577269 = 31577426
163 + 31577263 = 31577426
193 + 31577233 = 31577426
229 + 31577197 = 31577426

Showing the first eight; more decompositions exist.
