Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474330, here are decompositions:

11 + 31474319 = 31474330
23 + 31474307 = 31474330
29 + 31474301 = 31474330
113 + 31474217 = 31474330
257 + 31474073 = 31474330
269 + 31474061 = 31474330
353 + 31473977 = 31474330
359 + 31473971 = 31474330

Showing the first eight; more decompositions exist.
