Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454598, here are decompositions:

11 + 31454587 = 31454598
101 + 31454497 = 31454598
137 + 31454461 = 31454598
157 + 31454441 = 31454598
167 + 31454431 = 31454598
277 + 31454321 = 31454598
349 + 31454249 = 31454598
379 + 31454219 = 31454598

Showing the first eight; more decompositions exist.
