Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492084, here are decompositions:

3 + 31492081 = 31492084
5 + 31492079 = 31492084
11 + 31492073 = 31492084
17 + 31492067 = 31492084
23 + 31492061 = 31492084
53 + 31492031 = 31492084
101 + 31491983 = 31492084
167 + 31491917 = 31492084

Showing the first eight; more decompositions exist.
