Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542360, here are decompositions:

19 + 31542341 = 31542360
37 + 31542323 = 31542360
79 + 31542281 = 31542360
127 + 31542233 = 31542360
131 + 31542229 = 31542360
163 + 31542197 = 31542360
197 + 31542163 = 31542360
211 + 31542149 = 31542360

Showing the first eight; more decompositions exist.
