Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488098, here are decompositions:

7 + 31488091 = 31488098
67 + 31488031 = 31488098
79 + 31488019 = 31488098
157 + 31487941 = 31488098
181 + 31487917 = 31488098
457 + 31487641 = 31488098
547 + 31487551 = 31488098
571 + 31487527 = 31488098

Showing the first eight; more decompositions exist.
