Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574088, here are decompositions:
- 17 + 31574071 = 31574088
- 41 + 31574047 = 31574088
- 47 + 31574041 = 31574088
- 67 + 31574021 = 31574088
- 89 + 31573999 = 31574088
- 127 + 31573961 = 31574088
- 131 + 31573957 = 31574088
- 157 + 31573931 = 31574088
Showing the first eight; more decompositions exist.
