Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603060, here are decompositions:

101 + 31602959 = 31603060
197 + 31602863 = 31603060
257 + 31602803 = 31603060
479 + 31602581 = 31603060
521 + 31602539 = 31603060
563 + 31602497 = 31603060
617 + 31602443 = 31603060
659 + 31602401 = 31603060

Showing the first eight; more decompositions exist.
