Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562348, here are decompositions:

19 + 31562329 = 31562348
67 + 31562281 = 31562348
211 + 31562137 = 31562348
229 + 31562119 = 31562348
241 + 31562107 = 31562348
331 + 31562017 = 31562348
379 + 31561969 = 31562348
409 + 31561939 = 31562348

Showing the first eight; more decompositions exist.
