Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603922, here are decompositions:

3 + 31603919 = 31603922
43 + 31603879 = 31603922
79 + 31603843 = 31603922
211 + 31603711 = 31603922
241 + 31603681 = 31603922
313 + 31603609 = 31603922
433 + 31603489 = 31603922
541 + 31603381 = 31603922

Showing the first eight; more decompositions exist.
