Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482434, here are decompositions:

7 + 31482427 = 31482434
97 + 31482337 = 31482434
127 + 31482307 = 31482434
157 + 31482277 = 31482434
163 + 31482271 = 31482434
331 + 31482103 = 31482434
337 + 31482097 = 31482434
367 + 31482067 = 31482434

Showing the first eight; more decompositions exist.
