Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528792, here are decompositions:

41 + 31528751 = 31528792
179 + 31528613 = 31528792
233 + 31528559 = 31528792
293 + 31528499 = 31528792
359 + 31528433 = 31528792
419 + 31528373 = 31528792
443 + 31528349 = 31528792
479 + 31528313 = 31528792

Showing the first eight; more decompositions exist.
