Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577334, here are decompositions:

11 + 31577323 = 31577334
43 + 31577291 = 31577334
71 + 31577263 = 31577334
73 + 31577261 = 31577334
101 + 31577233 = 31577334
137 + 31577197 = 31577334
251 + 31577083 = 31577334
263 + 31577071 = 31577334

Showing the first eight; more decompositions exist.
