Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603664, here are decompositions:

7 + 31603657 = 31603664
97 + 31603567 = 31603664
271 + 31603393 = 31603664
283 + 31603381 = 31603664
523 + 31603141 = 31603664
541 + 31603123 = 31603664
691 + 31602973 = 31603664
733 + 31602931 = 31603664

Showing the first eight; more decompositions exist.
