Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498392, here are decompositions:

43 + 31498349 = 31498392
103 + 31498289 = 31498392
113 + 31498279 = 31498392
139 + 31498253 = 31498392
179 + 31498213 = 31498392
193 + 31498199 = 31498392
199 + 31498193 = 31498392
241 + 31498151 = 31498392

Showing the first eight; more decompositions exist.
