Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534002, here are decompositions:

23 + 31533979 = 31534002
43 + 31533959 = 31534002
53 + 31533949 = 31534002
79 + 31533923 = 31534002
83 + 31533919 = 31534002
131 + 31533871 = 31534002
163 + 31533839 = 31534002
173 + 31533829 = 31534002

Showing the first eight; more decompositions exist.
