Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562774, here are decompositions:

7 + 31562767 = 31562774
37 + 31562737 = 31562774
97 + 31562677 = 31562774
151 + 31562623 = 31562774
157 + 31562617 = 31562774
163 + 31562611 = 31562774
181 + 31562593 = 31562774
223 + 31562551 = 31562774

Showing the first eight; more decompositions exist.
