Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474622, here are decompositions:

73 + 31474549 = 31474622
103 + 31474519 = 31474622
199 + 31474423 = 31474622
271 + 31474351 = 31474622
331 + 31474291 = 31474622
373 + 31474249 = 31474622
409 + 31474213 = 31474622
631 + 31473991 = 31474622

Showing the first eight; more decompositions exist.
