Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455292, here are decompositions:

23 + 31455269 = 31455292
53 + 31455239 = 31455292
83 + 31455209 = 31455292
131 + 31455161 = 31455292
173 + 31455119 = 31455292
251 + 31455041 = 31455292
293 + 31454999 = 31455292
383 + 31454909 = 31455292

Showing the first eight; more decompositions exist.
