Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482476, here are decompositions:

37 + 31482439 = 31482476
127 + 31482349 = 31482476
139 + 31482337 = 31482476
199 + 31482277 = 31482476
229 + 31482247 = 31482476
307 + 31482169 = 31482476
373 + 31482103 = 31482476
379 + 31482097 = 31482476

Showing the first eight; more decompositions exist.
