Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499122, here are decompositions:

59 + 31499063 = 31499122
89 + 31499033 = 31499122
101 + 31499021 = 31499122
131 + 31498991 = 31499122
173 + 31498949 = 31499122
191 + 31498931 = 31499122
269 + 31498853 = 31499122
293 + 31498829 = 31499122

Showing the first eight; more decompositions exist.
