Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588792, here are decompositions:

83 + 31588709 = 31588792
113 + 31588679 = 31588792
149 + 31588643 = 31588792
269 + 31588523 = 31588792
353 + 31588439 = 31588792
461 + 31588331 = 31588792
479 + 31588313 = 31588792
593 + 31588199 = 31588792

Showing the first eight; more decompositions exist.
