Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602390, here are decompositions:

23 + 31602367 = 31602390
37 + 31602353 = 31602390
67 + 31602323 = 31602390
73 + 31602317 = 31602390
109 + 31602281 = 31602390
139 + 31602251 = 31602390
151 + 31602239 = 31602390
163 + 31602227 = 31602390

Showing the first eight; more decompositions exist.
