Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462754, here are decompositions:

3 + 31462751 = 31462754
7 + 31462747 = 31462754
31 + 31462723 = 31462754
151 + 31462603 = 31462754
163 + 31462591 = 31462754
181 + 31462573 = 31462754
223 + 31462531 = 31462754
283 + 31462471 = 31462754

Showing the first eight; more decompositions exist.
