Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460932, here are decompositions:

3 + 31460929 = 31460932
5 + 31460927 = 31460932
53 + 31460879 = 31460932
59 + 31460873 = 31460932
101 + 31460831 = 31460932
149 + 31460783 = 31460932
383 + 31460549 = 31460932
449 + 31460483 = 31460932

Showing the first eight; more decompositions exist.
