Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498304, here are decompositions:

31 + 31498273 = 31498304
181 + 31498123 = 31498304
193 + 31498111 = 31498304
307 + 31497997 = 31498304
373 + 31497931 = 31498304
421 + 31497883 = 31498304
433 + 31497871 = 31498304
547 + 31497757 = 31498304

Showing the first eight; more decompositions exist.
