Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475098, here are decompositions:

29 + 31475069 = 31475098
89 + 31475009 = 31475098
101 + 31474997 = 31475098
167 + 31474931 = 31475098
269 + 31474829 = 31475098
521 + 31474577 = 31475098
617 + 31474481 = 31475098
701 + 31474397 = 31475098

Showing the first eight; more decompositions exist.
