Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444898, here are decompositions:

7 + 31444891 = 31444898
19 + 31444879 = 31444898
61 + 31444837 = 31444898
97 + 31444801 = 31444898
109 + 31444789 = 31444898
127 + 31444771 = 31444898
139 + 31444759 = 31444898
181 + 31444717 = 31444898

Showing the first eight; more decompositions exist.
