Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562102, here are decompositions:

3 + 31562099 = 31562102
79 + 31562023 = 31562102
109 + 31561993 = 31562102
163 + 31561939 = 31562102
199 + 31561903 = 31562102
349 + 31561753 = 31562102
373 + 31561729 = 31562102
379 + 31561723 = 31562102

Showing the first eight; more decompositions exist.
