Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498292, here are decompositions:

3 + 31498289 = 31498292
13 + 31498279 = 31498292
19 + 31498273 = 31498292
79 + 31498213 = 31498292
103 + 31498189 = 31498292
181 + 31498111 = 31498292
223 + 31498069 = 31498292
283 + 31498009 = 31498292

Showing the first eight; more decompositions exist.
