Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535700, here are decompositions:

19 + 31535681 = 31535700
29 + 31535671 = 31535700
43 + 31535657 = 31535700
61 + 31535639 = 31535700
67 + 31535633 = 31535700
107 + 31535593 = 31535700
109 + 31535591 = 31535700
149 + 31535551 = 31535700

Showing the first eight; more decompositions exist.
