Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603814, here are decompositions:

13 + 31603801 = 31603814
97 + 31603717 = 31603814
103 + 31603711 = 31603814
157 + 31603657 = 31603814
421 + 31603393 = 31603814
433 + 31603381 = 31603814
673 + 31603141 = 31603814
691 + 31603123 = 31603814

Showing the first eight; more decompositions exist.
