Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454846, here are decompositions:

19 + 31454827 = 31454846
37 + 31454809 = 31454846
109 + 31454737 = 31454846
193 + 31454653 = 31454846
349 + 31454497 = 31454846
457 + 31454389 = 31454846
463 + 31454383 = 31454846
769 + 31454077 = 31454846

Showing the first eight; more decompositions exist.
