Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498482, here are decompositions:

11 + 31498471 = 31498482
13 + 31498469 = 31498482
19 + 31498463 = 31498482
61 + 31498421 = 31498482
139 + 31498343 = 31498482
193 + 31498289 = 31498482
229 + 31498253 = 31498482
269 + 31498213 = 31498482

Showing the first eight; more decompositions exist.
