Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603182, here are decompositions:

41 + 31603141 = 31603182
43 + 31603139 = 31603182
59 + 31603123 = 31603182
71 + 31603111 = 31603182
73 + 31603109 = 31603182
103 + 31603079 = 31603182
109 + 31603073 = 31603182
173 + 31603009 = 31603182

Showing the first eight; more decompositions exist.
