Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498370, here are decompositions:

3 + 31498367 = 31498370
97 + 31498273 = 31498370
157 + 31498213 = 31498370
181 + 31498189 = 31498370
283 + 31498087 = 31498370
331 + 31498039 = 31498370
367 + 31498003 = 31498370
373 + 31497997 = 31498370

Showing the first eight; more decompositions exist.
