Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485332, here are decompositions:

13 + 31485319 = 31485332
19 + 31485313 = 31485332
31 + 31485301 = 31485332
139 + 31485193 = 31485332
211 + 31485121 = 31485332
283 + 31485049 = 31485332
313 + 31485019 = 31485332
331 + 31485001 = 31485332

Showing the first eight; more decompositions exist.
