Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468402, here are decompositions:

3 + 31468399 = 31468402
5 + 31468397 = 31468402
11 + 31468391 = 31468402
71 + 31468331 = 31468402
83 + 31468319 = 31468402
113 + 31468289 = 31468402
131 + 31468271 = 31468402
179 + 31468223 = 31468402

Showing the first eight; more decompositions exist.
