Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460340, here are decompositions:

11 + 31460329 = 31460340
19 + 31460321 = 31460340
47 + 31460293 = 31460340
59 + 31460281 = 31460340
61 + 31460279 = 31460340
73 + 31460267 = 31460340
167 + 31460173 = 31460340
173 + 31460167 = 31460340

Showing the first eight; more decompositions exist.
