Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480260, here are decompositions:

59 + 31480201 = 31480260
131 + 31480129 = 31480260
157 + 31480103 = 31480260
181 + 31480079 = 31480260
199 + 31480061 = 31480260
211 + 31480049 = 31480260
239 + 31480021 = 31480260
241 + 31480019 = 31480260

Showing the first eight; more decompositions exist.
