Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602142, here are decompositions:

71 + 31602071 = 31602142
101 + 31602041 = 31602142
251 + 31601891 = 31602142
269 + 31601873 = 31602142
293 + 31601849 = 31602142
359 + 31601783 = 31602142
419 + 31601723 = 31602142
431 + 31601711 = 31602142

Showing the first eight; more decompositions exist.
