Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605410, here are decompositions:

3 + 31605407 = 31605410
61 + 31605349 = 31605410
139 + 31605271 = 31605410
163 + 31605247 = 31605410
181 + 31605229 = 31605410
229 + 31605181 = 31605410
241 + 31605169 = 31605410
271 + 31605139 = 31605410

Showing the first eight; more decompositions exist.
