Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522098, here are decompositions:

7 + 31522091 = 31522098
37 + 31522061 = 31522098
79 + 31522019 = 31522098
107 + 31521991 = 31522098
211 + 31521887 = 31522098
269 + 31521829 = 31522098
359 + 31521739 = 31522098
431 + 31521667 = 31522098

Showing the first eight; more decompositions exist.
