Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447092, here are decompositions:

11 + 31447081 = 31447092
13 + 31447079 = 31447092
23 + 31447069 = 31447092
71 + 31447021 = 31447092
73 + 31447019 = 31447092
109 + 31446983 = 31447092
139 + 31446953 = 31447092
199 + 31446893 = 31447092

Showing the first eight; more decompositions exist.
