Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488476, here are decompositions:

7 + 31488469 = 31488476
13 + 31488463 = 31488476
43 + 31488433 = 31488476
367 + 31488109 = 31488476
457 + 31488019 = 31488476
463 + 31488013 = 31488476
499 + 31487977 = 31488476
673 + 31487803 = 31488476

Showing the first eight; more decompositions exist.
