Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448498, here are decompositions:

19 + 31448479 = 31448498
199 + 31448299 = 31448498
307 + 31448191 = 31448498
337 + 31448161 = 31448498
349 + 31448149 = 31448498
541 + 31447957 = 31448498
547 + 31447951 = 31448498
661 + 31447837 = 31448498

Showing the first eight; more decompositions exist.
