Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488062, here are decompositions:

3 + 31488059 = 31488062
31 + 31488031 = 31488062
43 + 31488019 = 31488062
283 + 31487779 = 31488062
421 + 31487641 = 31488062
523 + 31487539 = 31488062
643 + 31487419 = 31488062
733 + 31487329 = 31488062

Showing the first eight; more decompositions exist.
