Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544198, here are decompositions:

19 + 31544179 = 31544198
31 + 31544167 = 31544198
67 + 31544131 = 31544198
109 + 31544089 = 31544198
157 + 31544041 = 31544198
211 + 31543987 = 31544198
271 + 31543927 = 31544198
421 + 31543777 = 31544198

Showing the first eight; more decompositions exist.
