Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498674, here are decompositions:

17 + 31498657 = 31498674
83 + 31498591 = 31498674
127 + 31498547 = 31498674
157 + 31498517 = 31498674
211 + 31498463 = 31498674
307 + 31498367 = 31498674
331 + 31498343 = 31498674
367 + 31498307 = 31498674

Showing the first eight; more decompositions exist.
