Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460574, here are decompositions:

23 + 31460551 = 31460574
37 + 31460537 = 31460574
83 + 31460491 = 31460574
227 + 31460347 = 31460574
281 + 31460293 = 31460574
283 + 31460291 = 31460574
293 + 31460281 = 31460574
307 + 31460267 = 31460574

Showing the first eight; more decompositions exist.
