Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473374, here are decompositions:

43 + 31473331 = 31473374
61 + 31473313 = 31473374
157 + 31473217 = 31473374
211 + 31473163 = 31473374
223 + 31473151 = 31473374
307 + 31473067 = 31473374
313 + 31473061 = 31473374
337 + 31473037 = 31473374

Showing the first eight; more decompositions exist.
