Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628102, here are decompositions:

3 + 31628099 = 31628102
13 + 31628089 = 31628102
199 + 31627903 = 31628102
223 + 31627879 = 31628102
241 + 31627861 = 31628102
349 + 31627753 = 31628102
463 + 31627639 = 31628102
601 + 31627501 = 31628102

Showing the first eight; more decompositions exist.
