Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534242, here are decompositions:

11 + 31534231 = 31534242
43 + 31534199 = 31534242
59 + 31534183 = 31534242
73 + 31534169 = 31534242
101 + 31534141 = 31534242
139 + 31534103 = 31534242
163 + 31534079 = 31534242
191 + 31534051 = 31534242

Showing the first eight; more decompositions exist.
