Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540962, here are decompositions:

23 + 31540939 = 31540962
41 + 31540921 = 31540962
139 + 31540823 = 31540962
149 + 31540813 = 31540962
179 + 31540783 = 31540962
239 + 31540723 = 31540962
263 + 31540699 = 31540962
269 + 31540693 = 31540962

Showing the first eight; more decompositions exist.
