Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557834, here are decompositions:

23 + 31557811 = 31557834
43 + 31557791 = 31557834
47 + 31557787 = 31557834
73 + 31557761 = 31557834
101 + 31557733 = 31557834
103 + 31557731 = 31557834
131 + 31557703 = 31557834
137 + 31557697 = 31557834

Showing the first eight; more decompositions exist.
