Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464538, here are decompositions:

29 + 31464509 = 31464538
137 + 31464401 = 31464538
179 + 31464359 = 31464538
197 + 31464341 = 31464538
257 + 31464281 = 31464538
269 + 31464269 = 31464538
389 + 31464149 = 31464538
401 + 31464137 = 31464538

Showing the first eight; more decompositions exist.
