Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480536, here are decompositions:

7 + 31480529 = 31480536
29 + 31480507 = 31480536
103 + 31480433 = 31480536
163 + 31480373 = 31480536
167 + 31480369 = 31480536
277 + 31480259 = 31480536
419 + 31480117 = 31480536
433 + 31480103 = 31480536

Showing the first eight; more decompositions exist.
