Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445348, here are decompositions:

79 + 31445269 = 31445348
127 + 31445221 = 31445348
211 + 31445137 = 31445348
241 + 31445107 = 31445348
307 + 31445041 = 31445348
331 + 31445017 = 31445348
409 + 31444939 = 31445348
457 + 31444891 = 31445348

Showing the first eight; more decompositions exist.
