Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498350, here are decompositions:

7 + 31498343 = 31498350
43 + 31498307 = 31498350
61 + 31498289 = 31498350
71 + 31498279 = 31498350
73 + 31498277 = 31498350
97 + 31498253 = 31498350
137 + 31498213 = 31498350
151 + 31498199 = 31498350

Showing the first eight; more decompositions exist.
