Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472104, here are decompositions:

101 + 31472003 = 31472104
113 + 31471991 = 31472104
137 + 31471967 = 31472104
197 + 31471907 = 31472104
281 + 31471823 = 31472104
317 + 31471787 = 31472104
401 + 31471703 = 31472104
467 + 31471637 = 31472104

Showing the first eight; more decompositions exist.
