Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554950, here are decompositions:

3 + 31554947 = 31554950
61 + 31554889 = 31554950
67 + 31554883 = 31554950
109 + 31554841 = 31554950
127 + 31554823 = 31554950
139 + 31554811 = 31554950
211 + 31554739 = 31554950
241 + 31554709 = 31554950

Showing the first eight; more decompositions exist.
