Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603030, here are decompositions:

3 + 31603027 = 31603030
71 + 31602959 = 31603030
113 + 31602917 = 31603030
131 + 31602899 = 31603030
167 + 31602863 = 31603030
227 + 31602803 = 31603030
383 + 31602647 = 31603030
443 + 31602587 = 31603030

Showing the first eight; more decompositions exist.
