Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628084, here are decompositions:

67 + 31628017 = 31628084
73 + 31628011 = 31628084
157 + 31627927 = 31628084
181 + 31627903 = 31628084
223 + 31627861 = 31628084
283 + 31627801 = 31628084
331 + 31627753 = 31628084
457 + 31627627 = 31628084

Showing the first eight; more decompositions exist.
