Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562598, here are decompositions:

5 + 31562593 = 31562598
31 + 31562567 = 31562598
47 + 31562551 = 31562598
79 + 31562519 = 31562598
97 + 31562501 = 31562598
131 + 31562467 = 31562598
149 + 31562449 = 31562598
157 + 31562441 = 31562598

Showing the first eight; more decompositions exist.
