Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602718, here are decompositions:

29 + 31602689 = 31602718
71 + 31602647 = 31602718
131 + 31602587 = 31602718
137 + 31602581 = 31602718
179 + 31602539 = 31602718
197 + 31602521 = 31602718
317 + 31602401 = 31602718
401 + 31602317 = 31602718

Showing the first eight; more decompositions exist.
