Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557734, here are decompositions:

3 + 31557731 = 31557734
31 + 31557703 = 31557734
37 + 31557697 = 31557734
97 + 31557637 = 31557734
181 + 31557553 = 31557734
211 + 31557523 = 31557734
223 + 31557511 = 31557734
367 + 31557367 = 31557734

Showing the first eight; more decompositions exist.
