Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468206, here are decompositions:

5 + 31468201 = 31468206
37 + 31468169 = 31468206
47 + 31468159 = 31468206
59 + 31468147 = 31468206
109 + 31468097 = 31468206
139 + 31468067 = 31468206
179 + 31468027 = 31468206
193 + 31468013 = 31468206

Showing the first eight; more decompositions exist.
