Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446046, here are decompositions:

89 + 31445957 = 31446046
197 + 31445849 = 31446046
257 + 31445789 = 31446046
353 + 31445693 = 31446046
383 + 31445663 = 31446046
503 + 31445543 = 31446046
557 + 31445489 = 31446046
587 + 31445459 = 31446046

Showing the first eight; more decompositions exist.
