Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446424, here are decompositions:

83 + 31446341 = 31446424
101 + 31446323 = 31446424
167 + 31446257 = 31446424
173 + 31446251 = 31446424
197 + 31446227 = 31446424
257 + 31446167 = 31446424
293 + 31446131 = 31446424
467 + 31445957 = 31446424

Showing the first eight; more decompositions exist.
