Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599418, here are decompositions:

29 + 31599389 = 31599418
317 + 31599101 = 31599418
359 + 31599059 = 31599418
479 + 31598939 = 31599418
491 + 31598927 = 31599418
509 + 31598909 = 31599418
647 + 31598771 = 31599418
701 + 31598717 = 31599418

Showing the first eight; more decompositions exist.
