Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520296, here are decompositions:

53 + 31520243 = 31520296
179 + 31520117 = 31520296
359 + 31519937 = 31520296
419 + 31519877 = 31520296
503 + 31519793 = 31520296
593 + 31519703 = 31520296
617 + 31519679 = 31520296
809 + 31519487 = 31520296

Showing the first eight; more decompositions exist.
