Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562802, here are decompositions:

23 + 31562779 = 31562802
179 + 31562623 = 31562802
181 + 31562621 = 31562802
191 + 31562611 = 31562802
199 + 31562603 = 31562802
251 + 31562551 = 31562802
283 + 31562519 = 31562802
353 + 31562449 = 31562802

Showing the first eight; more decompositions exist.
