Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468390, here are decompositions:

53 + 31468337 = 31468390
59 + 31468331 = 31468390
71 + 31468319 = 31468390
101 + 31468289 = 31468390
131 + 31468259 = 31468390
167 + 31468223 = 31468390
179 + 31468211 = 31468390
293 + 31468097 = 31468390

Showing the first eight; more decompositions exist.
