Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454894, here are decompositions:

13 + 31454881 = 31454894
67 + 31454827 = 31454894
157 + 31454737 = 31454894
193 + 31454701 = 31454894
241 + 31454653 = 31454894
307 + 31454587 = 31454894
397 + 31454497 = 31454894
433 + 31454461 = 31454894

Showing the first eight; more decompositions exist.
