Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474682, here are decompositions:

13 + 31474669 = 31474682
163 + 31474519 = 31474682
181 + 31474501 = 31474682
193 + 31474489 = 31474682
331 + 31474351 = 31474682
433 + 31474249 = 31474682
541 + 31474141 = 31474682
571 + 31474111 = 31474682

Showing the first eight; more decompositions exist.
