Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454738, here are decompositions:

37 + 31454701 = 31454738
151 + 31454587 = 31454738
241 + 31454497 = 31454738
277 + 31454461 = 31454738
307 + 31454431 = 31454738
349 + 31454389 = 31454738
541 + 31454197 = 31454738
547 + 31454191 = 31454738

Showing the first eight; more decompositions exist.
