Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446694, here are decompositions:

5 + 31446689 = 31446694
53 + 31446641 = 31446694
101 + 31446593 = 31446694
131 + 31446563 = 31446694
137 + 31446557 = 31446694
233 + 31446461 = 31446694
353 + 31446341 = 31446694
443 + 31446251 = 31446694

Showing the first eight; more decompositions exist.
