Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477098, here are decompositions:

19 + 31477079 = 31477098
31 + 31477067 = 31477098
41 + 31477057 = 31477098
47 + 31477051 = 31477098
71 + 31477027 = 31477098
139 + 31476959 = 31477098
151 + 31476947 = 31477098
167 + 31476931 = 31477098

Showing the first eight; more decompositions exist.
