Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453002, here are decompositions:

29 + 31452973 = 31453002
59 + 31452943 = 31453002
101 + 31452901 = 31453002
151 + 31452851 = 31453002
173 + 31452829 = 31453002
199 + 31452803 = 31453002
233 + 31452769 = 31453002
239 + 31452763 = 31453002

Showing the first eight; more decompositions exist.
