Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562982, here are decompositions:

23 + 31562959 = 31562982
71 + 31562911 = 31562982
181 + 31562801 = 31562982
271 + 31562711 = 31562982
359 + 31562623 = 31562982
379 + 31562603 = 31562982
389 + 31562593 = 31562982
431 + 31562551 = 31562982

Showing the first eight; more decompositions exist.
