Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574202, here are decompositions:

29 + 31574173 = 31574202
71 + 31574131 = 31574202
103 + 31574099 = 31574202
109 + 31574093 = 31574202
131 + 31574071 = 31574202
181 + 31574021 = 31574202
241 + 31573961 = 31574202
271 + 31573931 = 31574202

Showing the first eight; more decompositions exist.
