Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603742, here are decompositions:

3 + 31603739 = 31603742
31 + 31603711 = 31603742
61 + 31603681 = 31603742
223 + 31603519 = 31603742
349 + 31603393 = 31603742
433 + 31603309 = 31603742
601 + 31603141 = 31603742
619 + 31603123 = 31603742

Showing the first eight; more decompositions exist.
