Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586602, here are decompositions:

11 + 31586591 = 31586602
23 + 31586579 = 31586602
59 + 31586543 = 31586602
101 + 31586501 = 31586602
251 + 31586351 = 31586602
263 + 31586339 = 31586602
431 + 31586171 = 31586602
461 + 31586141 = 31586602

Showing the first eight; more decompositions exist.
