Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471196, here are decompositions:

73 + 31471123 = 31471196
103 + 31471093 = 31471196
199 + 31470997 = 31471196
283 + 31470913 = 31471196
307 + 31470889 = 31471196
349 + 31470847 = 31471196
373 + 31470823 = 31471196
397 + 31470799 = 31471196

Showing the first eight; more decompositions exist.
