Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453098, here are decompositions:

59 + 31453039 = 31453098
197 + 31452901 = 31453098
239 + 31452859 = 31453098
269 + 31452829 = 31453098
349 + 31452749 = 31453098
359 + 31452739 = 31453098
367 + 31452731 = 31453098
379 + 31452719 = 31453098

Showing the first eight; more decompositions exist.
