Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449346, here are decompositions:

23 + 31449323 = 31449346
59 + 31449287 = 31449346
83 + 31449263 = 31449346
113 + 31449233 = 31449346
167 + 31449179 = 31449346
263 + 31449083 = 31449346
293 + 31449053 = 31449346
317 + 31449029 = 31449346

Showing the first eight; more decompositions exist.
