Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577594, here are decompositions:

3 + 31577591 = 31577594
7 + 31577587 = 31577594
67 + 31577527 = 31577594
73 + 31577521 = 31577594
193 + 31577401 = 31577594
211 + 31577383 = 31577594
241 + 31577353 = 31577594
271 + 31577323 = 31577594

Showing the first eight; more decompositions exist.
