Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535364, here are decompositions:

23 + 31535341 = 31535364
37 + 31535327 = 31535364
43 + 31535321 = 31535364
53 + 31535311 = 31535364
101 + 31535263 = 31535364
131 + 31535233 = 31535364
137 + 31535227 = 31535364
151 + 31535213 = 31535364

Showing the first eight; more decompositions exist.
