Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603066, here are decompositions:

107 + 31602959 = 31603066
149 + 31602917 = 31603066
167 + 31602899 = 31603066
263 + 31602803 = 31603066
419 + 31602647 = 31603066
479 + 31602587 = 31603066
569 + 31602497 = 31603066
743 + 31602323 = 31603066

Showing the first eight; more decompositions exist.
