Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535484, here are decompositions:

17 + 31535467 = 31535484
61 + 31535423 = 31535484
67 + 31535417 = 31535484
73 + 31535411 = 31535484
103 + 31535381 = 31535484
107 + 31535377 = 31535484
157 + 31535327 = 31535484
163 + 31535321 = 31535484

Showing the first eight; more decompositions exist.
