Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534346, here are decompositions:

3 + 31534343 = 31534346
13 + 31534333 = 31534346
163 + 31534183 = 31534346
229 + 31534117 = 31534346
313 + 31534033 = 31534346
367 + 31533979 = 31534346
379 + 31533967 = 31534346
397 + 31533949 = 31534346

Showing the first eight; more decompositions exist.
