Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541962, here are decompositions:

29 + 31541933 = 31541962
59 + 31541903 = 31541962
71 + 31541891 = 31541962
269 + 31541693 = 31541962
311 + 31541651 = 31541962
479 + 31541483 = 31541962
563 + 31541399 = 31541962
719 + 31541243 = 31541962

Showing the first eight; more decompositions exist.
