Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549260, here are decompositions:

19 + 31549241 = 31549260
23 + 31549237 = 31549260
53 + 31549207 = 31549260
59 + 31549201 = 31549260
79 + 31549181 = 31549260
173 + 31549087 = 31549260
179 + 31549081 = 31549260
241 + 31549019 = 31549260

Showing the first eight; more decompositions exist.
