Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535158, here are decompositions:

101 + 31535057 = 31535158
197 + 31534961 = 31535158
359 + 31534799 = 31535158
401 + 31534757 = 31535158
419 + 31534739 = 31535158
449 + 31534709 = 31535158
467 + 31534691 = 31535158
521 + 31534637 = 31535158

Showing the first eight; more decompositions exist.
