Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603974, here are decompositions:

41 + 31603933 = 31603974
43 + 31603931 = 31603974
97 + 31603877 = 31603974
131 + 31603843 = 31603974
173 + 31603801 = 31603974
223 + 31603751 = 31603974
257 + 31603717 = 31603974
263 + 31603711 = 31603974

Showing the first eight; more decompositions exist.
