Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472486, here are decompositions:

7 + 31472479 = 31472486
37 + 31472449 = 31472486
127 + 31472359 = 31472486
193 + 31472293 = 31472486
277 + 31472209 = 31472486
307 + 31472179 = 31472486
337 + 31472149 = 31472486
379 + 31472107 = 31472486

Showing the first eight; more decompositions exist.
