Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593446, here are decompositions:

103 + 31593343 = 31593446
139 + 31593307 = 31593446
193 + 31593253 = 31593446
337 + 31593109 = 31593446
349 + 31593097 = 31593446
463 + 31592983 = 31593446
487 + 31592959 = 31593446
499 + 31592947 = 31593446

Showing the first eight; more decompositions exist.
