Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147138, here are decompositions:
- 31 + 147107 = 147138
- 41 + 147097 = 147138
- 107 + 147031 = 147138
- 109 + 147029 = 147138
- 127 + 147011 = 147138
- 149 + 146989 = 147138
- 151 + 146987 = 147138
- 197 + 146941 = 147138
Showing the first eight; more decompositions exist.
