Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492206, here are decompositions:

43 + 31492163 = 31492206
113 + 31492093 = 31492206
127 + 31492079 = 31492206
139 + 31492067 = 31492206
173 + 31492033 = 31492206
223 + 31491983 = 31492206
293 + 31491913 = 31492206
313 + 31491893 = 31492206

Showing the first eight; more decompositions exist.
