Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464260, here are decompositions:

67 + 31464193 = 31464260
73 + 31464187 = 31464260
181 + 31464079 = 31464260
193 + 31464067 = 31464260
199 + 31464061 = 31464260
229 + 31464031 = 31464260
349 + 31463911 = 31464260
367 + 31463893 = 31464260

Showing the first eight; more decompositions exist.
