Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478596, here are decompositions:

3 + 31478593 = 31478596
29 + 31478567 = 31478596
113 + 31478483 = 31478596
167 + 31478429 = 31478596
197 + 31478399 = 31478596
263 + 31478333 = 31478596
269 + 31478327 = 31478596
449 + 31478147 = 31478596

Showing the first eight; more decompositions exist.
