Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598804, here are decompositions:

103 + 31598701 = 31598804
157 + 31598647 = 31598804
283 + 31598521 = 31598804
577 + 31598227 = 31598804
613 + 31598191 = 31598804
661 + 31598143 = 31598804
877 + 31597927 = 31598804
1087 + 31597717 = 31598804

Showing the first eight; more decompositions exist.
