Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562954, here are decompositions:

37 + 31562917 = 31562954
43 + 31562911 = 31562954
127 + 31562827 = 31562954
271 + 31562683 = 31562954
277 + 31562677 = 31562954
331 + 31562623 = 31562954
337 + 31562617 = 31562954
487 + 31562467 = 31562954

Showing the first eight; more decompositions exist.
