Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475102, here are decompositions:

3 + 31475099 = 31475102
13 + 31475089 = 31475102
19 + 31475083 = 31475102
31 + 31475071 = 31475102
73 + 31475029 = 31475102
103 + 31474999 = 31475102
229 + 31474873 = 31475102
409 + 31474693 = 31475102

Showing the first eight; more decompositions exist.
