Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472098, here are decompositions:

29 + 31472069 = 31472098
107 + 31471991 = 31472098
131 + 31471967 = 31472098
191 + 31471907 = 31472098
197 + 31471901 = 31472098
311 + 31471787 = 31472098
401 + 31471697 = 31472098
431 + 31471667 = 31472098

Showing the first eight; more decompositions exist.
