Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449616, here are decompositions:

5 + 31449611 = 31449616
47 + 31449569 = 31449616
59 + 31449557 = 31449616
89 + 31449527 = 31449616
137 + 31449479 = 31449616
167 + 31449449 = 31449616
239 + 31449377 = 31449616
257 + 31449359 = 31449616

Showing the first eight; more decompositions exist.
