Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593464, here are decompositions:

3 + 31593461 = 31593464
73 + 31593391 = 31593464
151 + 31593313 = 31593464
157 + 31593307 = 31593464
211 + 31593253 = 31593464
271 + 31593193 = 31593464
367 + 31593097 = 31593464
433 + 31593031 = 31593464

Showing the first eight; more decompositions exist.
