Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493346, here are decompositions:

7 + 31493339 = 31493346
23 + 31493323 = 31493346
97 + 31493249 = 31493346
193 + 31493153 = 31493346
263 + 31493083 = 31493346
277 + 31493069 = 31493346
293 + 31493053 = 31493346
307 + 31493039 = 31493346

Showing the first eight; more decompositions exist.
