Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484194, here are decompositions:

17 + 31484177 = 31484194
101 + 31484093 = 31484194
113 + 31484081 = 31484194
281 + 31483913 = 31484194
311 + 31483883 = 31484194
317 + 31483877 = 31484194
353 + 31483841 = 31484194
461 + 31483733 = 31484194

Showing the first eight; more decompositions exist.
