Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602842, here are decompositions:

79 + 31602763 = 31602842
151 + 31602691 = 31602842
163 + 31602679 = 31602842
181 + 31602661 = 31602842
211 + 31602631 = 31602842
421 + 31602421 = 31602842
919 + 31601923 = 31602842
1033 + 31601809 = 31602842

Showing the first eight; more decompositions exist.
