Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472382, here are decompositions:

23 + 31472359 = 31472382
31 + 31472351 = 31472382
43 + 31472339 = 31472382
89 + 31472293 = 31472382
173 + 31472209 = 31472382
181 + 31472201 = 31472382
191 + 31472191 = 31472382
199 + 31472183 = 31472382

Showing the first eight; more decompositions exist.
