Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498302, here are decompositions:

13 + 31498289 = 31498302
23 + 31498279 = 31498302
29 + 31498273 = 31498302
89 + 31498213 = 31498302
103 + 31498199 = 31498302
109 + 31498193 = 31498302
113 + 31498189 = 31498302
151 + 31498151 = 31498302

Showing the first eight; more decompositions exist.
