Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484856, here are decompositions:

17 + 31484839 = 31484856
19 + 31484837 = 31484856
59 + 31484797 = 31484856
79 + 31484777 = 31484856
103 + 31484753 = 31484856
157 + 31484699 = 31484856
229 + 31484627 = 31484856
239 + 31484617 = 31484856

Showing the first eight; more decompositions exist.
