Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505174, here are decompositions:

31 + 31505143 = 31505174
37 + 31505137 = 31505174
97 + 31505077 = 31505174
193 + 31504981 = 31505174
223 + 31504951 = 31505174
271 + 31504903 = 31505174
373 + 31504801 = 31505174
523 + 31504651 = 31505174

Showing the first eight; more decompositions exist.
