Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603274, here are decompositions:

13 + 31603261 = 31603274
127 + 31603147 = 31603274
151 + 31603123 = 31603274
163 + 31603111 = 31603274
397 + 31602877 = 31603274
421 + 31602853 = 31603274
601 + 31602673 = 31603274
613 + 31602661 = 31603274

Showing the first eight; more decompositions exist.
