Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475204, here are decompositions:

73 + 31475131 = 31475204
97 + 31475107 = 31475204
151 + 31475053 = 31475204
223 + 31474981 = 31475204
331 + 31474873 = 31475204
337 + 31474867 = 31475204
421 + 31474783 = 31475204
457 + 31474747 = 31475204

Showing the first eight; more decompositions exist.
