Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472452, here are decompositions:

3 + 31472449 = 31472452
101 + 31472351 = 31472452
113 + 31472339 = 31472452
191 + 31472261 = 31472452
251 + 31472201 = 31472452
269 + 31472183 = 31472452
293 + 31472159 = 31472452
383 + 31472069 = 31472452

Showing the first eight; more decompositions exist.
