Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535174, here are decompositions:

3 + 31535171 = 31535174
31 + 31535143 = 31535174
43 + 31535131 = 31535174
61 + 31535113 = 31535174
67 + 31535107 = 31535174
163 + 31535011 = 31535174
193 + 31534981 = 31535174
373 + 31534801 = 31535174

Showing the first eight; more decompositions exist.
