Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484756, here are decompositions:

3 + 31484753 = 31484756
109 + 31484647 = 31484756
139 + 31484617 = 31484756
223 + 31484533 = 31484756
307 + 31484449 = 31484756
379 + 31484377 = 31484756
397 + 31484359 = 31484756
439 + 31484317 = 31484756

Showing the first eight; more decompositions exist.
