Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465202, here are decompositions:

19 + 31465183 = 31465202
73 + 31465129 = 31465202
79 + 31465123 = 31465202
103 + 31465099 = 31465202
163 + 31465039 = 31465202
199 + 31465003 = 31465202
211 + 31464991 = 31465202
229 + 31464973 = 31465202

Showing the first eight; more decompositions exist.
