Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498454, here are decompositions:

181 + 31498273 = 31498454
241 + 31498213 = 31498454
331 + 31498123 = 31498454
367 + 31498087 = 31498454
457 + 31497997 = 31498454
523 + 31497931 = 31498454
571 + 31497883 = 31498454
727 + 31497727 = 31498454

Showing the first eight; more decompositions exist.
