Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473012, here are decompositions:

29 + 31472983 = 31473012
83 + 31472929 = 31473012
163 + 31472849 = 31473012
173 + 31472839 = 31473012
199 + 31472813 = 31473012
239 + 31472773 = 31473012
313 + 31472699 = 31473012
349 + 31472663 = 31473012

Showing the first eight; more decompositions exist.
