Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475504, here are decompositions:

13 + 31475491 = 31475504
61 + 31475443 = 31475504
97 + 31475407 = 31475504
103 + 31475401 = 31475504
163 + 31475341 = 31475504
373 + 31475131 = 31475504
397 + 31475107 = 31475504
421 + 31475083 = 31475504

Showing the first eight; more decompositions exist.
