Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460902, here are decompositions:

23 + 31460879 = 31460902
29 + 31460873 = 31460902
71 + 31460831 = 31460902
173 + 31460729 = 31460902
293 + 31460609 = 31460902
353 + 31460549 = 31460902
419 + 31460483 = 31460902
461 + 31460441 = 31460902

Showing the first eight; more decompositions exist.
