Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474348, here are decompositions:

5 + 31474343 = 31474348
29 + 31474319 = 31474348
41 + 31474307 = 31474348
47 + 31474301 = 31474348
131 + 31474217 = 31474348
431 + 31473917 = 31474348
461 + 31473887 = 31474348
509 + 31473839 = 31474348

Showing the first eight; more decompositions exist.
