Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498260, here are decompositions:

7 + 31498253 = 31498260
43 + 31498217 = 31498260
47 + 31498213 = 31498260
61 + 31498199 = 31498260
67 + 31498193 = 31498260
71 + 31498189 = 31498260
109 + 31498151 = 31498260
137 + 31498123 = 31498260

Showing the first eight; more decompositions exist.
