Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88190, here are decompositions:
- 13 + 88177 = 88190
- 61 + 88129 = 88190
- 73 + 88117 = 88190
- 97 + 88093 = 88190
- 199 + 87991 = 88190
- 229 + 87961 = 88190
- 313 + 87877 = 88190
- 337 + 87853 = 88190
Showing the first eight; more decompositions exist.
