Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446396, here are decompositions:

29 + 31446367 = 31446396
67 + 31446329 = 31446396
73 + 31446323 = 31446396
139 + 31446257 = 31446396
167 + 31446229 = 31446396
173 + 31446223 = 31446396
229 + 31446167 = 31446396
263 + 31446133 = 31446396

Showing the first eight; more decompositions exist.
