Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480232, here are decompositions:

31 + 31480201 = 31480232
103 + 31480129 = 31480232
211 + 31480021 = 31480232
271 + 31479961 = 31480232
283 + 31479949 = 31480232
439 + 31479793 = 31480232
463 + 31479769 = 31480232
613 + 31479619 = 31480232

Showing the first eight; more decompositions exist.
