Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628302, here are decompositions:

11 + 31628291 = 31628302
29 + 31628273 = 31628302
53 + 31628249 = 31628302
131 + 31628171 = 31628302
281 + 31628021 = 31628302
353 + 31627949 = 31628302
491 + 31627811 = 31628302
509 + 31627793 = 31628302

Showing the first eight; more decompositions exist.
