Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535318, here are decompositions:

7 + 31535311 = 31535318
211 + 31535107 = 31535318
307 + 31535011 = 31535318
337 + 31534981 = 31535318
439 + 31534879 = 31535318
487 + 31534831 = 31535318
499 + 31534819 = 31535318
757 + 31534561 = 31535318

Showing the first eight; more decompositions exist.
