Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446676, here are decompositions:

83 + 31446593 = 31446676
113 + 31446563 = 31446676
347 + 31446329 = 31446676
353 + 31446323 = 31446676
419 + 31446257 = 31446676
449 + 31446227 = 31446676
509 + 31446167 = 31446676
719 + 31445957 = 31446676

Showing the first eight; more decompositions exist.
