Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460590, here are decompositions:

41 + 31460549 = 31460590
53 + 31460537 = 31460590
107 + 31460483 = 31460590
149 + 31460441 = 31460590
191 + 31460399 = 31460590
251 + 31460339 = 31460590
269 + 31460321 = 31460590
311 + 31460279 = 31460590

Showing the first eight; more decompositions exist.
