Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482430, here are decompositions:

3 + 31482427 = 31482430
29 + 31482401 = 31482430
41 + 31482389 = 31482430
137 + 31482293 = 31482430
149 + 31482281 = 31482430
173 + 31482257 = 31482430
251 + 31482179 = 31482430
257 + 31482173 = 31482430

Showing the first eight; more decompositions exist.
