Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482450, here are decompositions:

11 + 31482439 = 31482450
23 + 31482427 = 31482450
61 + 31482389 = 31482450
101 + 31482349 = 31482450
107 + 31482343 = 31482450
113 + 31482337 = 31482450
157 + 31482293 = 31482450
173 + 31482277 = 31482450

Showing the first eight; more decompositions exist.
