Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562760, here are decompositions:

23 + 31562737 = 31562760
83 + 31562677 = 31562760
137 + 31562623 = 31562760
139 + 31562621 = 31562760
149 + 31562611 = 31562760
157 + 31562603 = 31562760
167 + 31562593 = 31562760
193 + 31562567 = 31562760

Showing the first eight; more decompositions exist.
