Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455976, here are decompositions:

17 + 31455959 = 31455976
29 + 31455947 = 31455976
47 + 31455929 = 31455976
107 + 31455869 = 31455976
173 + 31455803 = 31455976
263 + 31455713 = 31455976
353 + 31455623 = 31455976
443 + 31455533 = 31455976

Showing the first eight; more decompositions exist.
