Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482566, here are decompositions:

7 + 31482559 = 31482566
67 + 31482499 = 31482566
127 + 31482439 = 31482566
139 + 31482427 = 31482566
223 + 31482343 = 31482566
229 + 31482337 = 31482566
337 + 31482229 = 31482566
397 + 31482169 = 31482566

Showing the first eight; more decompositions exist.
