Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562744, here are decompositions:

7 + 31562737 = 31562744
61 + 31562683 = 31562744
67 + 31562677 = 31562744
127 + 31562617 = 31562744
151 + 31562593 = 31562744
193 + 31562551 = 31562744
277 + 31562467 = 31562744
313 + 31562431 = 31562744

Showing the first eight; more decompositions exist.
