Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520548, here are decompositions:

11 + 31520537 = 31520548
29 + 31520519 = 31520548
131 + 31520417 = 31520548
149 + 31520399 = 31520548
239 + 31520309 = 31520548
347 + 31520201 = 31520548
431 + 31520117 = 31520548
659 + 31519889 = 31520548

Showing the first eight; more decompositions exist.
