Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472424, here are decompositions:

73 + 31472351 = 31472424
131 + 31472293 = 31472424
163 + 31472261 = 31472424
223 + 31472201 = 31472424
233 + 31472191 = 31472424
241 + 31472183 = 31472424
257 + 31472167 = 31472424
271 + 31472153 = 31472424

Showing the first eight; more decompositions exist.
