Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455010, here are decompositions:

11 + 31454999 = 31455010
53 + 31454957 = 31455010
101 + 31454909 = 31455010
107 + 31454903 = 31455010
137 + 31454873 = 31455010
173 + 31454837 = 31455010
227 + 31454783 = 31455010
269 + 31454741 = 31455010

Showing the first eight; more decompositions exist.
