Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488050, here are decompositions:

19 + 31488031 = 31488050
31 + 31488019 = 31488050
37 + 31488013 = 31488050
73 + 31487977 = 31488050
109 + 31487941 = 31488050
271 + 31487779 = 31488050
409 + 31487641 = 31488050
499 + 31487551 = 31488050

Showing the first eight; more decompositions exist.
