Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458804, here are decompositions:

5 + 31458799 = 31458804
7 + 31458797 = 31458804
17 + 31458787 = 31458804
43 + 31458761 = 31458804
101 + 31458703 = 31458804
103 + 31458701 = 31458804
107 + 31458697 = 31458804
137 + 31458667 = 31458804

Showing the first eight; more decompositions exist.
