Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603510, here are decompositions:

23 + 31603487 = 31603510
83 + 31603427 = 31603510
149 + 31603361 = 31603510
167 + 31603343 = 31603510
251 + 31603259 = 31603510
317 + 31603193 = 31603510
353 + 31603157 = 31603510
401 + 31603109 = 31603510

Showing the first eight; more decompositions exist.
