Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446682, here are decompositions:

41 + 31446641 = 31446682
89 + 31446593 = 31446682
149 + 31446533 = 31446682
191 + 31446491 = 31446682
353 + 31446329 = 31446682
359 + 31446323 = 31446682
431 + 31446251 = 31446682
821 + 31445861 = 31446682

Showing the first eight; more decompositions exist.
