Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504460, here are decompositions:

7 + 31504453 = 31504460
73 + 31504387 = 31504460
103 + 31504357 = 31504460
109 + 31504351 = 31504460
157 + 31504303 = 31504460
241 + 31504219 = 31504460
271 + 31504189 = 31504460
277 + 31504183 = 31504460

Showing the first eight; more decompositions exist.
