Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484898, here are decompositions:

59 + 31484839 = 31484898
61 + 31484837 = 31484898
97 + 31484801 = 31484898
101 + 31484797 = 31484898
127 + 31484771 = 31484898
157 + 31484741 = 31484898
199 + 31484699 = 31484898
251 + 31484647 = 31484898

Showing the first eight; more decompositions exist.
