Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598048, here are decompositions:

19 + 31598029 = 31598048
37 + 31598011 = 31598048
61 + 31597987 = 31598048
271 + 31597777 = 31598048
331 + 31597717 = 31598048
397 + 31597651 = 31598048
409 + 31597639 = 31598048
499 + 31597549 = 31598048

Showing the first eight; more decompositions exist.
