Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602346, here are decompositions:

23 + 31602323 = 31602346
29 + 31602317 = 31602346
107 + 31602239 = 31602346
173 + 31602173 = 31602346
359 + 31601987 = 31602346
449 + 31601897 = 31602346
509 + 31601837 = 31602346
563 + 31601783 = 31602346

Showing the first eight; more decompositions exist.
