Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554962, here are decompositions:

13 + 31554949 = 31554962
73 + 31554889 = 31554962
79 + 31554883 = 31554962
139 + 31554823 = 31554962
151 + 31554811 = 31554962
223 + 31554739 = 31554962
331 + 31554631 = 31554962
349 + 31554613 = 31554962

Showing the first eight; more decompositions exist.
