Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474604, here are decompositions:

3 + 31474601 = 31474604
103 + 31474501 = 31474604
181 + 31474423 = 31474604
241 + 31474363 = 31474604
313 + 31474291 = 31474604
433 + 31474171 = 31474604
463 + 31474141 = 31474604
547 + 31474057 = 31474604

Showing the first eight; more decompositions exist.
