Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603426, here are decompositions:

59 + 31603367 = 31603426
83 + 31603343 = 31603426
167 + 31603259 = 31603426
233 + 31603193 = 31603426
269 + 31603157 = 31603426
317 + 31603109 = 31603426
347 + 31603079 = 31603426
353 + 31603073 = 31603426

Showing the first eight; more decompositions exist.
