Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535904, here are decompositions:

73 + 31535831 = 31535904
83 + 31535821 = 31535904
107 + 31535797 = 31535904
151 + 31535753 = 31535904
157 + 31535747 = 31535904
163 + 31535741 = 31535904
223 + 31535681 = 31535904
233 + 31535671 = 31535904

Showing the first eight; more decompositions exist.
