Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555046, here are decompositions:

97 + 31554949 = 31555046
157 + 31554889 = 31555046
163 + 31554883 = 31555046
223 + 31554823 = 31555046
307 + 31554739 = 31555046
337 + 31554709 = 31555046
379 + 31554667 = 31555046
409 + 31554637 = 31555046

Showing the first eight; more decompositions exist.
