Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482708, here are decompositions:

41 + 31482667 = 31482708
67 + 31482641 = 31482708
109 + 31482599 = 31482708
139 + 31482569 = 31482708
149 + 31482559 = 31482708
157 + 31482551 = 31482708
197 + 31482511 = 31482708
199 + 31482509 = 31482708

Showing the first eight; more decompositions exist.
