Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562908, here are decompositions:

59 + 31562849 = 31562908
107 + 31562801 = 31562908
131 + 31562777 = 31562908
197 + 31562711 = 31562908
281 + 31562627 = 31562908
389 + 31562519 = 31562908
467 + 31562441 = 31562908
479 + 31562429 = 31562908

Showing the first eight; more decompositions exist.
