Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449706, here are decompositions:

5 + 31449701 = 31449706
17 + 31449689 = 31449706
59 + 31449647 = 31449706
137 + 31449569 = 31449706
149 + 31449557 = 31449706
179 + 31449527 = 31449706
227 + 31449479 = 31449706
257 + 31449449 = 31449706

Showing the first eight; more decompositions exist.
