Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482318, here are decompositions:

11 + 31482307 = 31482318
37 + 31482281 = 31482318
41 + 31482277 = 31482318
47 + 31482271 = 31482318
61 + 31482257 = 31482318
71 + 31482247 = 31482318
89 + 31482229 = 31482318
139 + 31482179 = 31482318

Showing the first eight; more decompositions exist.
