Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535740, here are decompositions:

23 + 31535717 = 31535740
59 + 31535681 = 31535740
83 + 31535657 = 31535740
101 + 31535639 = 31535740
107 + 31535633 = 31535740
149 + 31535591 = 31535740
191 + 31535549 = 31535740
311 + 31535429 = 31535740

Showing the first eight; more decompositions exist.
