Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516292, here are decompositions:

103 + 31516189 = 31516292
109 + 31516183 = 31516292
139 + 31516153 = 31516292
163 + 31516129 = 31516292
193 + 31516099 = 31516292
211 + 31516081 = 31516292
271 + 31516021 = 31516292
373 + 31515919 = 31516292

Showing the first eight; more decompositions exist.
