Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562962, here are decompositions:

3 + 31562959 = 31562962
113 + 31562849 = 31562962
251 + 31562711 = 31562962
359 + 31562603 = 31562962
419 + 31562543 = 31562962
443 + 31562519 = 31562962
461 + 31562501 = 31562962
479 + 31562483 = 31562962

Showing the first eight; more decompositions exist.
