Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472284, here are decompositions:

23 + 31472261 = 31472284
83 + 31472201 = 31472284
101 + 31472183 = 31472284
131 + 31472153 = 31472284
281 + 31472003 = 31472284
293 + 31471991 = 31472284
317 + 31471967 = 31472284
383 + 31471901 = 31472284

Showing the first eight; more decompositions exist.
