Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599446, here are decompositions:

7 + 31599439 = 31599446
97 + 31599349 = 31599446
139 + 31599307 = 31599446
199 + 31599247 = 31599446
457 + 31598989 = 31599446
499 + 31598947 = 31599446
523 + 31598923 = 31599446
607 + 31598839 = 31599446

Showing the first eight; more decompositions exist.
