Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603548, here are decompositions:

29 + 31603519 = 31603548
37 + 31603511 = 31603548
59 + 31603489 = 31603548
61 + 31603487 = 31603548
167 + 31603381 = 31603548
181 + 31603367 = 31603548
239 + 31603309 = 31603548
401 + 31603147 = 31603548

Showing the first eight; more decompositions exist.
