Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583042, here are decompositions:

19 + 31583023 = 31583042
61 + 31582981 = 31583042
151 + 31582891 = 31583042
223 + 31582819 = 31583042
313 + 31582729 = 31583042
409 + 31582633 = 31583042
433 + 31582609 = 31583042
571 + 31582471 = 31583042

Showing the first eight; more decompositions exist.
