Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484100, here are decompositions:

7 + 31484093 = 31484100
19 + 31484081 = 31484100
29 + 31484071 = 31484100
31 + 31484069 = 31484100
41 + 31484059 = 31484100
173 + 31483927 = 31484100
181 + 31483919 = 31484100
211 + 31483889 = 31484100

Showing the first eight; more decompositions exist.
