Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506294, here are decompositions:

11 + 31506283 = 31506294
23 + 31506271 = 31506294
31 + 31506263 = 31506294
47 + 31506247 = 31506294
101 + 31506193 = 31506294
191 + 31506103 = 31506294
223 + 31506071 = 31506294
233 + 31506061 = 31506294

Showing the first eight; more decompositions exist.
