Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537104, here are decompositions:

7 + 31537097 = 31537104
17 + 31537087 = 31537104
61 + 31537043 = 31537104
101 + 31537003 = 31537104
103 + 31537001 = 31537104
113 + 31536991 = 31537104
167 + 31536937 = 31537104
233 + 31536871 = 31537104

Showing the first eight; more decompositions exist.
