Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603482, here are decompositions:

89 + 31603393 = 31603482
101 + 31603381 = 31603482
139 + 31603343 = 31603482
173 + 31603309 = 31603482
223 + 31603259 = 31603482
233 + 31603249 = 31603482
359 + 31603123 = 31603482
373 + 31603109 = 31603482

Showing the first eight; more decompositions exist.
