Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461992, here are decompositions:

13 + 31461979 = 31461992
31 + 31461961 = 31461992
43 + 31461949 = 31461992
73 + 31461919 = 31461992
151 + 31461841 = 31461992
181 + 31461811 = 31461992
229 + 31461763 = 31461992
421 + 31461571 = 31461992

Showing the first eight; more decompositions exist.
