Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535260, here are decompositions:

41 + 31535219 = 31535260
47 + 31535213 = 31535260
89 + 31535171 = 31535260
137 + 31535123 = 31535260
179 + 31535081 = 31535260
227 + 31535033 = 31535260
347 + 31534913 = 31535260
389 + 31534871 = 31535260

Showing the first eight; more decompositions exist.
