Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603194, here are decompositions:

37 + 31603157 = 31603194
47 + 31603147 = 31603194
53 + 31603141 = 31603194
71 + 31603123 = 31603194
83 + 31603111 = 31603194
167 + 31603027 = 31603194
263 + 31602931 = 31603194
277 + 31602917 = 31603194

Showing the first eight; more decompositions exist.
