Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577604, here are decompositions:

11 + 31577593 = 31577604
13 + 31577591 = 31577604
17 + 31577587 = 31577604
73 + 31577531 = 31577604
83 + 31577521 = 31577604
131 + 31577473 = 31577604
211 + 31577393 = 31577604
241 + 31577363 = 31577604

Showing the first eight; more decompositions exist.
