Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554260, here are decompositions:

19 + 31554241 = 31554260
61 + 31554199 = 31554260
79 + 31554181 = 31554260
97 + 31554163 = 31554260
139 + 31554121 = 31554260
277 + 31553983 = 31554260
457 + 31553803 = 31554260
499 + 31553761 = 31554260

Showing the first eight; more decompositions exist.
