Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462046, here are decompositions:

43 + 31462003 = 31462046
67 + 31461979 = 31462046
97 + 31461949 = 31462046
103 + 31461943 = 31462046
127 + 31461919 = 31462046
223 + 31461823 = 31462046
229 + 31461817 = 31462046
283 + 31461763 = 31462046

Showing the first eight; more decompositions exist.
