Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562932, here are decompositions:

83 + 31562849 = 31562932
131 + 31562801 = 31562932
311 + 31562621 = 31562932
389 + 31562543 = 31562932
431 + 31562501 = 31562932
449 + 31562483 = 31562932
491 + 31562441 = 31562932
503 + 31562429 = 31562932

Showing the first eight; more decompositions exist.
