Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535424, here are decompositions:

5 + 31535419 = 31535424
7 + 31535417 = 31535424
13 + 31535411 = 31535424
43 + 31535381 = 31535424
47 + 31535377 = 31535424
83 + 31535341 = 31535424
97 + 31535327 = 31535424
103 + 31535321 = 31535424

Showing the first eight; more decompositions exist.
