Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473206, here are decompositions:

3 + 31473203 = 31473206
19 + 31473187 = 31473206
43 + 31473163 = 31473206
97 + 31473109 = 31473206
139 + 31473067 = 31473206
223 + 31472983 = 31473206
277 + 31472929 = 31473206
367 + 31472839 = 31473206

Showing the first eight; more decompositions exist.
