Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462726, here are decompositions:

3 + 31462723 = 31462726
137 + 31462589 = 31462726
149 + 31462577 = 31462726
173 + 31462553 = 31462726
179 + 31462547 = 31462726
293 + 31462433 = 31462726
353 + 31462373 = 31462726
509 + 31462217 = 31462726

Showing the first eight; more decompositions exist.
