Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483088, here are decompositions:

19 + 31483069 = 31483088
37 + 31483051 = 31483088
97 + 31482991 = 31483088
181 + 31482907 = 31483088
199 + 31482889 = 31483088
229 + 31482859 = 31483088
379 + 31482709 = 31483088
421 + 31482667 = 31483088

Showing the first eight; more decompositions exist.
