Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475524, here are decompositions:

53 + 31475471 = 31475524
71 + 31475453 = 31475524
131 + 31475393 = 31475524
137 + 31475387 = 31475524
281 + 31475243 = 31475524
293 + 31475231 = 31475524
383 + 31475141 = 31475524
593 + 31474931 = 31475524

Showing the first eight; more decompositions exist.
