Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446734, here are decompositions:

127 + 31446607 = 31446734
181 + 31446553 = 31446734
307 + 31446427 = 31446734
367 + 31446367 = 31446734
373 + 31446361 = 31446734
523 + 31446211 = 31446734
601 + 31446133 = 31446734
673 + 31446061 = 31446734

Showing the first eight; more decompositions exist.
