Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481060, here are decompositions:

3 + 31481057 = 31481060
97 + 31480963 = 31481060
181 + 31480879 = 31481060
199 + 31480861 = 31481060
211 + 31480849 = 31481060
367 + 31480693 = 31481060
379 + 31480681 = 31481060
421 + 31480639 = 31481060

Showing the first eight; more decompositions exist.
