Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603008, here are decompositions:

109 + 31602899 = 31603008
131 + 31602877 = 31603008
149 + 31602859 = 31603008
317 + 31602691 = 31603008
347 + 31602661 = 31603008
419 + 31602589 = 31603008
421 + 31602587 = 31603008
487 + 31602521 = 31603008

Showing the first eight; more decompositions exist.
