Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472246, here are decompositions:

7 + 31472239 = 31472246
37 + 31472209 = 31472246
67 + 31472179 = 31472246
79 + 31472167 = 31472246
97 + 31472149 = 31472246
103 + 31472143 = 31472246
139 + 31472107 = 31472246
193 + 31472053 = 31472246

Showing the first eight; more decompositions exist.
