Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467830, here are decompositions:

19 + 31467811 = 31467830
67 + 31467763 = 31467830
103 + 31467727 = 31467830
109 + 31467721 = 31467830
139 + 31467691 = 31467830
241 + 31467589 = 31467830
271 + 31467559 = 31467830
349 + 31467481 = 31467830

Showing the first eight; more decompositions exist.
