Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603300, here are decompositions:

41 + 31603259 = 31603300
107 + 31603193 = 31603300
191 + 31603109 = 31603300
227 + 31603073 = 31603300
383 + 31602917 = 31603300
401 + 31602899 = 31603300
653 + 31602647 = 31603300
719 + 31602581 = 31603300

Showing the first eight; more decompositions exist.
