Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535460, here are decompositions:

31 + 31535429 = 31535460
37 + 31535423 = 31535460
41 + 31535419 = 31535460
43 + 31535417 = 31535460
79 + 31535381 = 31535460
83 + 31535377 = 31535460
139 + 31535321 = 31535460
149 + 31535311 = 31535460

Showing the first eight; more decompositions exist.
