Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540202, here are decompositions:

13 + 31540189 = 31540202
79 + 31540123 = 31540202
103 + 31540099 = 31540202
139 + 31540063 = 31540202
193 + 31540009 = 31540202
271 + 31539931 = 31540202
313 + 31539889 = 31540202
439 + 31539763 = 31540202

Showing the first eight; more decompositions exist.
