Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514554, here are decompositions:

3 + 31514551 = 31514554
17 + 31514537 = 31514554
41 + 31514513 = 31514554
131 + 31514423 = 31514554
257 + 31514297 = 31514554
263 + 31514291 = 31514554
293 + 31514261 = 31514554
587 + 31513967 = 31514554

Showing the first eight; more decompositions exist.
