Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535194, here are decompositions:

11 + 31535183 = 31535194
23 + 31535171 = 31535194
71 + 31535123 = 31535194
113 + 31535081 = 31535194
137 + 31535057 = 31535194
233 + 31534961 = 31535194
281 + 31534913 = 31535194
443 + 31534751 = 31535194

Showing the first eight; more decompositions exist.
