Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452996, here are decompositions:

19 + 31452977 = 31452996
23 + 31452973 = 31452996
53 + 31452943 = 31452996
137 + 31452859 = 31452996
167 + 31452829 = 31452996
193 + 31452803 = 31452996
227 + 31452769 = 31452996
233 + 31452763 = 31452996

Showing the first eight; more decompositions exist.
