Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455046, here are decompositions:

5 + 31455041 = 31455046
47 + 31454999 = 31455046
89 + 31454957 = 31455046
137 + 31454909 = 31455046
173 + 31454873 = 31455046
179 + 31454867 = 31455046
263 + 31454783 = 31455046
419 + 31454627 = 31455046

Showing the first eight; more decompositions exist.
