Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482952, here are decompositions:

5 + 31482947 = 31482952
113 + 31482839 = 31482952
131 + 31482821 = 31482952
173 + 31482779 = 31482952
191 + 31482761 = 31482952
269 + 31482683 = 31482952
311 + 31482641 = 31482952
353 + 31482599 = 31482952

Showing the first eight; more decompositions exist.
