Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562252, here are decompositions:

199 + 31562053 = 31562252
229 + 31562023 = 31562252
283 + 31561969 = 31562252
313 + 31561939 = 31562252
349 + 31561903 = 31562252
499 + 31561753 = 31562252
523 + 31561729 = 31562252
541 + 31561711 = 31562252

Showing the first eight; more decompositions exist.
