Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187802, here are decompositions:
- 103 + 187699 = 187802
- 151 + 187651 = 187802
- 163 + 187639 = 187802
- 229 + 187573 = 187802
- 271 + 187531 = 187802
- 331 + 187471 = 187802
- 379 + 187423 = 187802
- 409 + 187393 = 187802
Showing the first eight; more decompositions exist.
