Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534140, here are decompositions:

19 + 31534121 = 31534140
23 + 31534117 = 31534140
37 + 31534103 = 31534140
61 + 31534079 = 31534140
67 + 31534073 = 31534140
73 + 31534067 = 31534140
83 + 31534057 = 31534140
89 + 31534051 = 31534140

Showing the first eight; more decompositions exist.
