Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577962, here are decompositions:

11 + 31577951 = 31577962
23 + 31577939 = 31577962
113 + 31577849 = 31577962
149 + 31577813 = 31577962
179 + 31577783 = 31577962
233 + 31577729 = 31577962
293 + 31577669 = 31577962
431 + 31577531 = 31577962

Showing the first eight; more decompositions exist.
