Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488094, here are decompositions:

3 + 31488091 = 31488094
5 + 31488089 = 31488094
23 + 31488071 = 31488094
41 + 31488053 = 31488094
101 + 31487993 = 31488094
137 + 31487957 = 31488094
227 + 31487867 = 31488094
311 + 31487783 = 31488094

Showing the first eight; more decompositions exist.
