Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535244, here are decompositions:

11 + 31535233 = 31535244
17 + 31535227 = 31535244
31 + 31535213 = 31535244
61 + 31535183 = 31535244
71 + 31535173 = 31535244
73 + 31535171 = 31535244
101 + 31535143 = 31535244
113 + 31535131 = 31535244

Showing the first eight; more decompositions exist.
