Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461366, here are decompositions:

5 + 31461361 = 31461366
17 + 31461349 = 31461366
23 + 31461343 = 31461366
73 + 31461293 = 31461366
113 + 31461253 = 31461366
137 + 31461229 = 31461366
173 + 31461193 = 31461366
193 + 31461173 = 31461366

Showing the first eight; more decompositions exist.
