Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535524, here are decompositions:

101 + 31535423 = 31535524
107 + 31535417 = 31535524
113 + 31535411 = 31535524
197 + 31535327 = 31535524
311 + 31535213 = 31535524
353 + 31535171 = 31535524
401 + 31535123 = 31535524
443 + 31535081 = 31535524

Showing the first eight; more decompositions exist.
