Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562704, here are decompositions:

83 + 31562621 = 31562704
101 + 31562603 = 31562704
137 + 31562567 = 31562704
263 + 31562441 = 31562704
281 + 31562423 = 31562704
347 + 31562357 = 31562704
431 + 31562273 = 31562704
443 + 31562261 = 31562704

Showing the first eight; more decompositions exist.
