Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541974, here are decompositions:

3 + 31541971 = 31541974
41 + 31541933 = 31541974
71 + 31541903 = 31541974
83 + 31541891 = 31541974
281 + 31541693 = 31541974
383 + 31541591 = 31541974
467 + 31541507 = 31541974
491 + 31541483 = 31541974

Showing the first eight; more decompositions exist.
