Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535830, here are decompositions:

3 + 31535827 = 31535830
83 + 31535747 = 31535830
89 + 31535741 = 31535830
113 + 31535717 = 31535830
149 + 31535681 = 31535830
173 + 31535657 = 31535830
191 + 31535639 = 31535830
197 + 31535633 = 31535830

Showing the first eight; more decompositions exist.
