Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467260, here are decompositions:

31 + 31467229 = 31467260
61 + 31467199 = 31467260
79 + 31467181 = 31467260
103 + 31467157 = 31467260
127 + 31467133 = 31467260
157 + 31467103 = 31467260
193 + 31467067 = 31467260
271 + 31466989 = 31467260

Showing the first eight; more decompositions exist.
