Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532354, here are decompositions:

13 + 31532341 = 31532354
31 + 31532323 = 31532354
127 + 31532227 = 31532354
151 + 31532203 = 31532354
241 + 31532113 = 31532354
283 + 31532071 = 31532354
433 + 31531921 = 31532354
541 + 31531813 = 31532354

Showing the first eight; more decompositions exist.
