Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603480, here are decompositions:

53 + 31603427 = 31603480
113 + 31603367 = 31603480
137 + 31603343 = 31603480
401 + 31603079 = 31603480
521 + 31602959 = 31603480
563 + 31602917 = 31603480
617 + 31602863 = 31603480
677 + 31602803 = 31603480

Showing the first eight; more decompositions exist.
