Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603500, here are decompositions:

11 + 31603489 = 31603500
13 + 31603487 = 31603500
73 + 31603427 = 31603500
107 + 31603393 = 31603500
139 + 31603361 = 31603500
157 + 31603343 = 31603500
191 + 31603309 = 31603500
239 + 31603261 = 31603500

Showing the first eight; more decompositions exist.
