Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456066, here are decompositions:

53 + 31456013 = 31456066
107 + 31455959 = 31456066
137 + 31455929 = 31456066
197 + 31455869 = 31456066
263 + 31455803 = 31456066
353 + 31455713 = 31456066
419 + 31455647 = 31456066
443 + 31455623 = 31456066

Showing the first eight; more decompositions exist.
