Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562984, here are decompositions:

3 + 31562981 = 31562984
67 + 31562917 = 31562984
73 + 31562911 = 31562984
157 + 31562827 = 31562984
307 + 31562677 = 31562984
367 + 31562617 = 31562984
373 + 31562611 = 31562984
433 + 31562551 = 31562984

Showing the first eight; more decompositions exist.
