Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535164, here are decompositions:

41 + 31535123 = 31535164
83 + 31535081 = 31535164
107 + 31535057 = 31535164
131 + 31535033 = 31535164
251 + 31534913 = 31535164
293 + 31534871 = 31535164
677 + 31534487 = 31535164
821 + 31534343 = 31535164

Showing the first eight; more decompositions exist.
