Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541734, here are decompositions:

41 + 31541693 = 31541734
83 + 31541651 = 31541734
101 + 31541633 = 31541734
137 + 31541597 = 31541734
227 + 31541507 = 31541734
251 + 31541483 = 31541734
317 + 31541417 = 31541734
467 + 31541267 = 31541734

Showing the first eight; more decompositions exist.
