Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535204, here are decompositions:

31 + 31535173 = 31535204
61 + 31535143 = 31535204
73 + 31535131 = 31535204
97 + 31535107 = 31535204
193 + 31535011 = 31535204
223 + 31534981 = 31535204
331 + 31534873 = 31535204
373 + 31534831 = 31535204

Showing the first eight; more decompositions exist.
