Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628234, here are decompositions:

61 + 31628173 = 31628234
67 + 31628167 = 31628234
73 + 31628161 = 31628234
223 + 31628011 = 31628234
307 + 31627927 = 31628234
331 + 31627903 = 31628234
373 + 31627861 = 31628234
433 + 31627801 = 31628234

Showing the first eight; more decompositions exist.
