Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599626, here are decompositions:

73 + 31599553 = 31599626
127 + 31599499 = 31599626
139 + 31599487 = 31599626
277 + 31599349 = 31599626
313 + 31599313 = 31599626
367 + 31599259 = 31599626
379 + 31599247 = 31599626
433 + 31599193 = 31599626

Showing the first eight; more decompositions exist.
