Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603754, here are decompositions:

3 + 31603751 = 31603754
37 + 31603717 = 31603754
43 + 31603711 = 31603754
73 + 31603681 = 31603754
97 + 31603657 = 31603754
373 + 31603381 = 31603754
607 + 31603147 = 31603754
613 + 31603141 = 31603754

Showing the first eight; more decompositions exist.
