Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583108, here are decompositions:

61 + 31583047 = 31583108
127 + 31582981 = 31583108
157 + 31582951 = 31583108
211 + 31582897 = 31583108
331 + 31582777 = 31583108
379 + 31582729 = 31583108
499 + 31582609 = 31583108
577 + 31582531 = 31583108

Showing the first eight; more decompositions exist.
