Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462874, here are decompositions:

43 + 31462831 = 31462874
67 + 31462807 = 31462874
103 + 31462771 = 31462874
127 + 31462747 = 31462874
151 + 31462723 = 31462874
271 + 31462603 = 31462874
283 + 31462591 = 31462874
367 + 31462507 = 31462874

Showing the first eight; more decompositions exist.
