Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484498, here are decompositions:

37 + 31484461 = 31484498
139 + 31484359 = 31484498
181 + 31484317 = 31484498
337 + 31484161 = 31484498
439 + 31484059 = 31484498
541 + 31483957 = 31484498
571 + 31483927 = 31484498
691 + 31483807 = 31484498

Showing the first eight; more decompositions exist.
