Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462348, here are decompositions:

59 + 31462289 = 31462348
131 + 31462217 = 31462348
461 + 31461887 = 31462348
557 + 31461791 = 31462348
569 + 31461779 = 31462348
587 + 31461761 = 31462348
1187 + 31461161 = 31462348
1301 + 31461047 = 31462348

Showing the first eight; more decompositions exist.
