Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602580, here are decompositions:

41 + 31602539 = 31602580
59 + 31602521 = 31602580
83 + 31602497 = 31602580
137 + 31602443 = 31602580
179 + 31602401 = 31602580
227 + 31602353 = 31602580
257 + 31602323 = 31602580
263 + 31602317 = 31602580

Showing the first eight; more decompositions exist.
