Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595100, here are decompositions:

37 + 31595063 = 31595100
41 + 31595059 = 31595100
79 + 31595021 = 31595100
101 + 31594999 = 31595100
109 + 31594991 = 31595100
113 + 31594987 = 31595100
137 + 31594963 = 31595100
139 + 31594961 = 31595100

Showing the first eight; more decompositions exist.
