Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446634, here are decompositions:

41 + 31446593 = 31446634
71 + 31446563 = 31446634
101 + 31446533 = 31446634
173 + 31446461 = 31446634
293 + 31446341 = 31446634
311 + 31446323 = 31446634
383 + 31446251 = 31446634
467 + 31446167 = 31446634

Showing the first eight; more decompositions exist.
