Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474592, here are decompositions:

43 + 31474549 = 31474592
73 + 31474519 = 31474592
103 + 31474489 = 31474592
229 + 31474363 = 31474592
241 + 31474351 = 31474592
379 + 31474213 = 31474592
421 + 31474171 = 31474592
463 + 31474129 = 31474592

Showing the first eight; more decompositions exist.
