Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602382, here are decompositions:

29 + 31602353 = 31602382
59 + 31602323 = 31602382
101 + 31602281 = 31602382
131 + 31602251 = 31602382
239 + 31602143 = 31602382
311 + 31602071 = 31602382
491 + 31601891 = 31602382
509 + 31601873 = 31602382

Showing the first eight; more decompositions exist.
