Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534206, here are decompositions:

7 + 31534199 = 31534206
19 + 31534187 = 31534206
23 + 31534183 = 31534206
37 + 31534169 = 31534206
89 + 31534117 = 31534206
103 + 31534103 = 31534206
127 + 31534079 = 31534206
139 + 31534067 = 31534206

Showing the first eight; more decompositions exist.
