Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603270, here are decompositions:

11 + 31603259 = 31603270
113 + 31603157 = 31603270
131 + 31603139 = 31603270
191 + 31603079 = 31603270
197 + 31603073 = 31603270
311 + 31602959 = 31603270
353 + 31602917 = 31603270
467 + 31602803 = 31603270

Showing the first eight; more decompositions exist.
