Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593246, here are decompositions:

53 + 31593193 = 31593246
73 + 31593173 = 31593246
137 + 31593109 = 31593246
149 + 31593097 = 31593246
199 + 31593047 = 31593246
263 + 31592983 = 31593246
397 + 31592849 = 31593246
449 + 31592797 = 31593246

Showing the first eight; more decompositions exist.
