Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532046, here are decompositions:

43 + 31532003 = 31532046
79 + 31531967 = 31532046
137 + 31531909 = 31532046
163 + 31531883 = 31532046
229 + 31531817 = 31532046
233 + 31531813 = 31532046
367 + 31531679 = 31532046
379 + 31531667 = 31532046

Showing the first eight; more decompositions exist.
