Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593254, here are decompositions:

3 + 31593251 = 31593254
61 + 31593193 = 31593254
157 + 31593097 = 31593254
223 + 31593031 = 31593254
271 + 31592983 = 31593254
283 + 31592971 = 31593254
307 + 31592947 = 31593254
331 + 31592923 = 31593254

Showing the first eight; more decompositions exist.
