Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484088, here are decompositions:

7 + 31484081 = 31484088
17 + 31484071 = 31484088
19 + 31484069 = 31484088
29 + 31484059 = 31484088
107 + 31483981 = 31484088
109 + 31483979 = 31484088
131 + 31483957 = 31484088
199 + 31483889 = 31484088

Showing the first eight; more decompositions exist.
