Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462960, here are decompositions:

29 + 31462931 = 31462960
59 + 31462901 = 31462960
71 + 31462889 = 31462960
83 + 31462877 = 31462960
149 + 31462811 = 31462960
167 + 31462793 = 31462960
311 + 31462649 = 31462960
383 + 31462577 = 31462960

Showing the first eight; more decompositions exist.
