Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603276, here are decompositions:

17 + 31603259 = 31603276
83 + 31603193 = 31603276
137 + 31603139 = 31603276
167 + 31603109 = 31603276
197 + 31603079 = 31603276
317 + 31602959 = 31603276
359 + 31602917 = 31603276
587 + 31602689 = 31603276

Showing the first eight; more decompositions exist.
