Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462174, here are decompositions:

41 + 31462133 = 31462174
47 + 31462127 = 31462174
71 + 31462103 = 31462174
167 + 31462007 = 31462174
197 + 31461977 = 31462174
251 + 31461923 = 31462174
281 + 31461893 = 31462174
383 + 31461791 = 31462174

Showing the first eight; more decompositions exist.
