Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535060, here are decompositions:

3 + 31535057 = 31535060
61 + 31534999 = 31535060
79 + 31534981 = 31535060
181 + 31534879 = 31535060
229 + 31534831 = 31535060
241 + 31534819 = 31535060
307 + 31534753 = 31535060
331 + 31534729 = 31535060

Showing the first eight; more decompositions exist.
