Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462758, here are decompositions:

7 + 31462751 = 31462758
11 + 31462747 = 31462758
29 + 31462729 = 31462758
109 + 31462649 = 31462758
149 + 31462609 = 31462758
167 + 31462591 = 31462758
179 + 31462579 = 31462758
181 + 31462577 = 31462758

Showing the first eight; more decompositions exist.
