Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602582, here are decompositions:

43 + 31602539 = 31602582
61 + 31602521 = 31602582
101 + 31602481 = 31602582
131 + 31602451 = 31602582
139 + 31602443 = 31602582
181 + 31602401 = 31602582
229 + 31602353 = 31602582
331 + 31602251 = 31602582

Showing the first eight; more decompositions exist.
