Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472852, here are decompositions:

3 + 31472849 = 31472852
13 + 31472839 = 31472852
79 + 31472773 = 31472852
241 + 31472611 = 31472852
373 + 31472479 = 31472852
613 + 31472239 = 31472852
643 + 31472209 = 31472852
661 + 31472191 = 31472852

Showing the first eight; more decompositions exist.
