Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593242, here are decompositions:

211 + 31593031 = 31593242
271 + 31592971 = 31593242
283 + 31592959 = 31593242
409 + 31592833 = 31593242
433 + 31592809 = 31593242
463 + 31592779 = 31593242
601 + 31592641 = 31593242
643 + 31592599 = 31593242

Showing the first eight; more decompositions exist.
