Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603844, here are decompositions:

43 + 31603801 = 31603844
127 + 31603717 = 31603844
163 + 31603681 = 31603844
277 + 31603567 = 31603844
463 + 31603381 = 31603844
733 + 31603111 = 31603844
967 + 31602877 = 31603844
991 + 31602853 = 31603844

Showing the first eight; more decompositions exist.
