Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546330, here are decompositions:

29 + 31546301 = 31546330
47 + 31546283 = 31546330
113 + 31546217 = 31546330
131 + 31546199 = 31546330
149 + 31546181 = 31546330
311 + 31546019 = 31546330
317 + 31546013 = 31546330
443 + 31545887 = 31546330

Showing the first eight; more decompositions exist.
