Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603244, here are decompositions:

97 + 31603147 = 31603244
103 + 31603141 = 31603244
271 + 31602973 = 31603244
313 + 31602931 = 31603244
367 + 31602877 = 31603244
571 + 31602673 = 31603244
613 + 31602631 = 31603244
727 + 31602517 = 31603244

Showing the first eight; more decompositions exist.
