Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623160, here are decompositions:

47 + 31623113 = 31623160
113 + 31623047 = 31623160
137 + 31623023 = 31623160
227 + 31622933 = 31623160
383 + 31622777 = 31623160
419 + 31622741 = 31623160
431 + 31622729 = 31623160
461 + 31622699 = 31623160

Showing the first eight; more decompositions exist.
