Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482510, here are decompositions:

11 + 31482499 = 31482510
71 + 31482439 = 31482510
83 + 31482427 = 31482510
109 + 31482401 = 31482510
167 + 31482343 = 31482510
173 + 31482337 = 31482510
229 + 31482281 = 31482510
233 + 31482277 = 31482510

Showing the first eight; more decompositions exist.
