Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446354, here are decompositions:

13 + 31446341 = 31446354
31 + 31446323 = 31446354
97 + 31446257 = 31446354
101 + 31446253 = 31446354
103 + 31446251 = 31446354
113 + 31446241 = 31446354
127 + 31446227 = 31446354
131 + 31446223 = 31446354

Showing the first eight; more decompositions exist.
