Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480824, here are decompositions:

31 + 31480793 = 31480824
61 + 31480763 = 31480824
131 + 31480693 = 31480824
317 + 31480507 = 31480824
383 + 31480441 = 31480824
433 + 31480391 = 31480824
443 + 31480381 = 31480824
457 + 31480367 = 31480824

Showing the first eight; more decompositions exist.
