Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535932, here are decompositions:

23 + 31535909 = 31535932
53 + 31535879 = 31535932
101 + 31535831 = 31535932
179 + 31535753 = 31535932
191 + 31535741 = 31535932
251 + 31535681 = 31535932
293 + 31535639 = 31535932
383 + 31535549 = 31535932

Showing the first eight; more decompositions exist.
