Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603826, here are decompositions:

109 + 31603717 = 31603826
307 + 31603519 = 31603826
337 + 31603489 = 31603826
433 + 31603393 = 31603826
577 + 31603249 = 31603826
853 + 31602973 = 31603826
967 + 31602859 = 31603826
1033 + 31602793 = 31603826

Showing the first eight; more decompositions exist.
