Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626054, here are decompositions:

13 + 31626041 = 31626054
43 + 31626011 = 31626054
67 + 31625987 = 31626054
73 + 31625981 = 31626054
101 + 31625953 = 31626054
137 + 31625917 = 31626054
211 + 31625843 = 31626054
233 + 31625821 = 31626054

Showing the first eight; more decompositions exist.
