Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462318, here are decompositions:

5 + 31462313 = 31462318
29 + 31462289 = 31462318
101 + 31462217 = 31462318
191 + 31462127 = 31462318
311 + 31462007 = 31462318
431 + 31461887 = 31462318
467 + 31461851 = 31462318
557 + 31461761 = 31462318

Showing the first eight; more decompositions exist.
