Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482420, here are decompositions:

19 + 31482401 = 31482420
31 + 31482389 = 31482420
71 + 31482349 = 31482420
83 + 31482337 = 31482420
113 + 31482307 = 31482420
127 + 31482293 = 31482420
139 + 31482281 = 31482420
149 + 31482271 = 31482420

Showing the first eight; more decompositions exist.
