Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445054, here are decompositions:

13 + 31445041 = 31445054
37 + 31445017 = 31445054
61 + 31444993 = 31445054
163 + 31444891 = 31445054
211 + 31444843 = 31445054
241 + 31444813 = 31445054
283 + 31444771 = 31445054
331 + 31444723 = 31445054

Showing the first eight; more decompositions exist.
