Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583222, here are decompositions:

199 + 31583023 = 31583222
241 + 31582981 = 31583222
271 + 31582951 = 31583222
331 + 31582891 = 31583222
613 + 31582609 = 31583222
691 + 31582531 = 31583222
709 + 31582513 = 31583222
733 + 31582489 = 31583222

Showing the first eight; more decompositions exist.
