Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499432, here are decompositions:

31 + 31499401 = 31499432
61 + 31499371 = 31499432
103 + 31499329 = 31499432
109 + 31499323 = 31499432
193 + 31499239 = 31499432
271 + 31499161 = 31499432
409 + 31499023 = 31499432
439 + 31498993 = 31499432

Showing the first eight; more decompositions exist.
