Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534446, here are decompositions:

5 + 31534441 = 31534446
17 + 31534429 = 31534446
19 + 31534427 = 31534446
23 + 31534423 = 31534446
103 + 31534343 = 31534446
113 + 31534333 = 31534446
149 + 31534297 = 31534446
199 + 31534247 = 31534446

Showing the first eight; more decompositions exist.
