Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472456, here are decompositions:

7 + 31472449 = 31472456
19 + 31472437 = 31472456
97 + 31472359 = 31472456
163 + 31472293 = 31472456
277 + 31472179 = 31472456
307 + 31472149 = 31472456
313 + 31472143 = 31472456
349 + 31472107 = 31472456

Showing the first eight; more decompositions exist.
