Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582462, here are decompositions:

53 + 31582409 = 31582462
59 + 31582403 = 31582462
269 + 31582193 = 31582462
419 + 31582043 = 31582462
479 + 31581983 = 31582462
599 + 31581863 = 31582462
683 + 31581779 = 31582462
701 + 31581761 = 31582462

Showing the first eight; more decompositions exist.
