Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480452, here are decompositions:

11 + 31480441 = 31480452
19 + 31480433 = 31480452
61 + 31480391 = 31480452
71 + 31480381 = 31480452
79 + 31480373 = 31480452
83 + 31480369 = 31480452
103 + 31480349 = 31480452
163 + 31480289 = 31480452

Showing the first eight; more decompositions exist.
