Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602622, here are decompositions:

41 + 31602581 = 31602622
83 + 31602539 = 31602622
101 + 31602521 = 31602622
179 + 31602443 = 31602622
269 + 31602353 = 31602622
383 + 31602239 = 31602622
449 + 31602173 = 31602622
479 + 31602143 = 31602622

Showing the first eight; more decompositions exist.
