Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452480, here are decompositions:

19 + 31452461 = 31452480
29 + 31452451 = 31452480
61 + 31452419 = 31452480
79 + 31452401 = 31452480
113 + 31452367 = 31452480
139 + 31452341 = 31452480
179 + 31452301 = 31452480
197 + 31452283 = 31452480

Showing the first eight; more decompositions exist.
