Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576548, here are decompositions:

7 + 31576541 = 31576548
19 + 31576529 = 31576548
37 + 31576511 = 31576548
71 + 31576477 = 31576548
89 + 31576459 = 31576548
109 + 31576439 = 31576548
131 + 31576417 = 31576548
137 + 31576411 = 31576548

Showing the first eight; more decompositions exist.
