Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602442, here are decompositions:

41 + 31602401 = 31602442
89 + 31602353 = 31602442
191 + 31602251 = 31602442
269 + 31602173 = 31602442
401 + 31602041 = 31602442
569 + 31601873 = 31602442
593 + 31601849 = 31602442
659 + 31601783 = 31602442

Showing the first eight; more decompositions exist.
