Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599262, here are decompositions:

3 + 31599259 = 31599262
89 + 31599173 = 31599262
353 + 31598909 = 31599262
389 + 31598873 = 31599262
479 + 31598783 = 31599262
491 + 31598771 = 31599262
509 + 31598753 = 31599262
593 + 31598669 = 31599262

Showing the first eight; more decompositions exist.
