Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541992, here are decompositions:

3 + 31541989 = 31541992
11 + 31541981 = 31541992
59 + 31541933 = 31541992
89 + 31541903 = 31541992
101 + 31541891 = 31541992
359 + 31541633 = 31541992
401 + 31541591 = 31541992
509 + 31541483 = 31541992

Showing the first eight; more decompositions exist.
