Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603462, here are decompositions:

101 + 31603361 = 31603462
269 + 31603193 = 31603462
353 + 31603109 = 31603462
383 + 31603079 = 31603462
389 + 31603073 = 31603462
503 + 31602959 = 31603462
563 + 31602899 = 31603462
599 + 31602863 = 31603462

Showing the first eight; more decompositions exist.
