Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610154, here are decompositions:

11 + 31610143 = 31610154
13 + 31610141 = 31610154
41 + 31610113 = 31610154
47 + 31610107 = 31610154
61 + 31610093 = 31610154
71 + 31610083 = 31610154
73 + 31610081 = 31610154
131 + 31610023 = 31610154

Showing the first eight; more decompositions exist.
