Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562108, here are decompositions:

139 + 31561969 = 31562108
181 + 31561927 = 31562108
307 + 31561801 = 31562108
379 + 31561729 = 31562108
397 + 31561711 = 31562108
439 + 31561669 = 31562108
757 + 31561351 = 31562108
937 + 31561171 = 31562108

Showing the first eight; more decompositions exist.
