Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468120, here are decompositions:

23 + 31468097 = 31468120
53 + 31468067 = 31468120
107 + 31468013 = 31468120
137 + 31467983 = 31468120
227 + 31467893 = 31468120
311 + 31467809 = 31468120
353 + 31467767 = 31468120
401 + 31467719 = 31468120

Showing the first eight; more decompositions exist.
