Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535394, here are decompositions:

13 + 31535381 = 31535394
17 + 31535377 = 31535394
53 + 31535341 = 31535394
67 + 31535327 = 31535394
73 + 31535321 = 31535394
83 + 31535311 = 31535394
131 + 31535263 = 31535394
167 + 31535227 = 31535394

Showing the first eight; more decompositions exist.
