Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454610, here are decompositions:

23 + 31454587 = 31454610
97 + 31454513 = 31454610
113 + 31454497 = 31454610
127 + 31454483 = 31454610
149 + 31454461 = 31454610
179 + 31454431 = 31454610
227 + 31454383 = 31454610
233 + 31454377 = 31454610

Showing the first eight; more decompositions exist.
