Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488848, here are decompositions:

229 + 31488619 = 31488848
367 + 31488481 = 31488848
379 + 31488469 = 31488848
577 + 31488271 = 31488848
739 + 31488109 = 31488848
757 + 31488091 = 31488848
829 + 31488019 = 31488848
907 + 31487941 = 31488848

Showing the first eight; more decompositions exist.
