Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534374, here are decompositions:

5 + 31534369 = 31534374
31 + 31534343 = 31534374
41 + 31534333 = 31534374
73 + 31534301 = 31534374
103 + 31534271 = 31534374
127 + 31534247 = 31534374
191 + 31534183 = 31534374
233 + 31534141 = 31534374

Showing the first eight; more decompositions exist.
