Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484112, here are decompositions:

19 + 31484093 = 31484112
31 + 31484081 = 31484112
41 + 31484071 = 31484112
43 + 31484069 = 31484112
53 + 31484059 = 31484112
131 + 31483981 = 31484112
193 + 31483919 = 31484112
199 + 31483913 = 31484112

Showing the first eight; more decompositions exist.
