Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477952, here are decompositions:

73 + 31477879 = 31477952
193 + 31477759 = 31477952
199 + 31477753 = 31477952
223 + 31477729 = 31477952
229 + 31477723 = 31477952
241 + 31477711 = 31477952
283 + 31477669 = 31477952
349 + 31477603 = 31477952

Showing the first eight; more decompositions exist.
