Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462906, here are decompositions:

5 + 31462901 = 31462906
17 + 31462889 = 31462906
29 + 31462877 = 31462906
113 + 31462793 = 31462906
149 + 31462757 = 31462906
257 + 31462649 = 31462906
317 + 31462589 = 31462906
353 + 31462553 = 31462906

Showing the first eight; more decompositions exist.
