Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600146, here are decompositions:

13 + 31600133 = 31600146
29 + 31600117 = 31600146
43 + 31600103 = 31600146
47 + 31600099 = 31600146
59 + 31600087 = 31600146
89 + 31600057 = 31600146
103 + 31600043 = 31600146
107 + 31600039 = 31600146

Showing the first eight; more decompositions exist.
