Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499106, here are decompositions:

29 + 31499077 = 31499106
43 + 31499063 = 31499106
73 + 31499033 = 31499106
83 + 31499023 = 31499106
103 + 31499003 = 31499106
113 + 31498993 = 31499106
139 + 31498967 = 31499106
157 + 31498949 = 31499106

Showing the first eight; more decompositions exist.
