Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462492, here are decompositions:

11 + 31462481 = 31462492
41 + 31462451 = 31462492
53 + 31462439 = 31462492
59 + 31462433 = 31462492
179 + 31462313 = 31462492
359 + 31462133 = 31462492
389 + 31462103 = 31462492
569 + 31461923 = 31462492

Showing the first eight; more decompositions exist.
