Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593628, here are decompositions:
- 137 + 31593491 = 31593628
- 149 + 31593479 = 31593628
- 167 + 31593461 = 31593628
- 191 + 31593437 = 31593628
- 239 + 31593389 = 31593628
- 251 + 31593377 = 31593628
- 431 + 31593197 = 31593628
- 617 + 31593011 = 31593628
Showing the first eight; more decompositions exist.
