Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474532, here are decompositions:

13 + 31474519 = 31474532
31 + 31474501 = 31474532
43 + 31474489 = 31474532
109 + 31474423 = 31474532
181 + 31474351 = 31474532
241 + 31474291 = 31474532
283 + 31474249 = 31474532
421 + 31474111 = 31474532

Showing the first eight; more decompositions exist.
