Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477196, here are decompositions:

97 + 31477099 = 31477196
139 + 31477057 = 31477196
349 + 31476847 = 31477196
367 + 31476829 = 31477196
397 + 31476799 = 31477196
463 + 31476733 = 31477196
739 + 31476457 = 31477196
823 + 31476373 = 31477196

Showing the first eight; more decompositions exist.
