Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462766, here are decompositions:

7 + 31462759 = 31462766
19 + 31462747 = 31462766
37 + 31462729 = 31462766
43 + 31462723 = 31462766
157 + 31462609 = 31462766
163 + 31462603 = 31462766
193 + 31462573 = 31462766
409 + 31462357 = 31462766

Showing the first eight; more decompositions exist.
