Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454498, here are decompositions:

37 + 31454461 = 31454498
67 + 31454431 = 31454498
109 + 31454389 = 31454498
277 + 31454221 = 31454498
307 + 31454191 = 31454498
337 + 31454161 = 31454498
349 + 31454149 = 31454498
421 + 31454077 = 31454498

Showing the first eight; more decompositions exist.
