Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482620, here are decompositions:

3 + 31482617 = 31482620
7 + 31482613 = 31482620
61 + 31482559 = 31482620
109 + 31482511 = 31482620
181 + 31482439 = 31482620
193 + 31482427 = 31482620
271 + 31482349 = 31482620
277 + 31482343 = 31482620

Showing the first eight; more decompositions exist.
