Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484254, here are decompositions:

17 + 31484237 = 31484254
47 + 31484207 = 31484254
173 + 31484081 = 31484254
383 + 31483871 = 31484254
521 + 31483733 = 31484254
563 + 31483691 = 31484254
677 + 31483577 = 31484254
701 + 31483553 = 31484254

Showing the first eight; more decompositions exist.
