Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535404, here are decompositions:

23 + 31535381 = 31535404
83 + 31535321 = 31535404
191 + 31535213 = 31535404
233 + 31535171 = 31535404
281 + 31535123 = 31535404
347 + 31535057 = 31535404
443 + 31534961 = 31535404
491 + 31534913 = 31535404

Showing the first eight; more decompositions exist.
