Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526850, here are decompositions:

31 + 31526819 = 31526850
41 + 31526809 = 31526850
59 + 31526791 = 31526850
73 + 31526777 = 31526850
79 + 31526771 = 31526850
97 + 31526753 = 31526850
101 + 31526749 = 31526850
127 + 31526723 = 31526850

Showing the first eight; more decompositions exist.
