Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446342, here are decompositions:

13 + 31446329 = 31446342
19 + 31446323 = 31446342
89 + 31446253 = 31446342
101 + 31446241 = 31446342
113 + 31446229 = 31446342
131 + 31446211 = 31446342
211 + 31446131 = 31446342
241 + 31446101 = 31446342

Showing the first eight; more decompositions exist.
