Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483346, here are decompositions:

19 + 31483327 = 31483346
109 + 31483237 = 31483346
229 + 31483117 = 31483346
277 + 31483069 = 31483346
373 + 31482973 = 31483346
439 + 31482907 = 31483346
457 + 31482889 = 31483346
487 + 31482859 = 31483346

Showing the first eight; more decompositions exist.
