Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446910, here are decompositions:

17 + 31446893 = 31446910
71 + 31446839 = 31446910
149 + 31446761 = 31446910
167 + 31446743 = 31446910
269 + 31446641 = 31446910
317 + 31446593 = 31446910
347 + 31446563 = 31446910
353 + 31446557 = 31446910

Showing the first eight; more decompositions exist.
