Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603108, here are decompositions:

29 + 31603079 = 31603108
149 + 31602959 = 31603108
191 + 31602917 = 31603108
419 + 31602689 = 31603108
461 + 31602647 = 31603108
521 + 31602587 = 31603108
569 + 31602539 = 31603108
587 + 31602521 = 31603108

Showing the first eight; more decompositions exist.
