Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577074, here are decompositions:

3 + 31577071 = 31577074
17 + 31577057 = 31577074
83 + 31576991 = 31577074
107 + 31576967 = 31577074
173 + 31576901 = 31577074
401 + 31576673 = 31577074
491 + 31576583 = 31577074
563 + 31576511 = 31577074

Showing the first eight; more decompositions exist.
