Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474548, here are decompositions:
- 29 + 31474519 = 31474548
- 47 + 31474501 = 31474548
- 59 + 31474489 = 31474548
- 67 + 31474481 = 31474548
- 151 + 31474397 = 31474548
- 191 + 31474357 = 31474548
- 197 + 31474351 = 31474548
- 229 + 31474319 = 31474548
Showing the first eight; more decompositions exist.
