Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456162, here are decompositions:

41 + 31456121 = 31456162
83 + 31456079 = 31456162
149 + 31456013 = 31456162
233 + 31455929 = 31456162
293 + 31455869 = 31456162
359 + 31455803 = 31456162
401 + 31455761 = 31456162
449 + 31455713 = 31456162

Showing the first eight; more decompositions exist.
