Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487056, here are decompositions:

23 + 31487033 = 31487056
89 + 31486967 = 31487056
197 + 31486859 = 31487056
317 + 31486739 = 31487056
347 + 31486709 = 31487056
443 + 31486613 = 31487056
563 + 31486493 = 31487056
593 + 31486463 = 31487056

Showing the first eight; more decompositions exist.
