Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610186, here are decompositions:

43 + 31610143 = 31610186
73 + 31610113 = 31610186
79 + 31610107 = 31610186
103 + 31610083 = 31610186
163 + 31610023 = 31610186
193 + 31609993 = 31610186
229 + 31609957 = 31610186
337 + 31609849 = 31610186

Showing the first eight; more decompositions exist.
