Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541966, here are decompositions:

67 + 31541899 = 31541966
73 + 31541893 = 31541966
97 + 31541869 = 31541966
109 + 31541857 = 31541966
139 + 31541827 = 31541966
229 + 31541737 = 31541966
307 + 31541659 = 31541966
397 + 31541569 = 31541966

Showing the first eight; more decompositions exist.
