Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472362, here are decompositions:

3 + 31472359 = 31472362
11 + 31472351 = 31472362
23 + 31472339 = 31472362
71 + 31472291 = 31472362
101 + 31472261 = 31472362
179 + 31472183 = 31472362
239 + 31472123 = 31472362
293 + 31472069 = 31472362

Showing the first eight; more decompositions exist.
