Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474458, here are decompositions:

61 + 31474397 = 31474458
101 + 31474357 = 31474458
107 + 31474351 = 31474458
139 + 31474319 = 31474458
151 + 31474307 = 31474458
157 + 31474301 = 31474458
167 + 31474291 = 31474458
241 + 31474217 = 31474458

Showing the first eight; more decompositions exist.
