Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474392, here are decompositions:

29 + 31474363 = 31474392
41 + 31474351 = 31474392
73 + 31474319 = 31474392
101 + 31474291 = 31474392
139 + 31474253 = 31474392
179 + 31474213 = 31474392
251 + 31474141 = 31474392
263 + 31474129 = 31474392

Showing the first eight; more decompositions exist.
