Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452498, here are decompositions:

5 + 31452493 = 31452498
17 + 31452481 = 31452498
37 + 31452461 = 31452498
47 + 31452451 = 31452498
79 + 31452419 = 31452498
97 + 31452401 = 31452498
131 + 31452367 = 31452498
157 + 31452341 = 31452498

Showing the first eight; more decompositions exist.
