Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446952, here are decompositions:

3 + 31446949 = 31446952
59 + 31446893 = 31446952
113 + 31446839 = 31446952
191 + 31446761 = 31446952
263 + 31446689 = 31446952
311 + 31446641 = 31446952
359 + 31446593 = 31446952
389 + 31446563 = 31446952

Showing the first eight; more decompositions exist.
