Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562602, here are decompositions:

59 + 31562543 = 31562602
83 + 31562519 = 31562602
101 + 31562501 = 31562602
173 + 31562429 = 31562602
179 + 31562423 = 31562602
311 + 31562291 = 31562602
359 + 31562243 = 31562602
389 + 31562213 = 31562602

Showing the first eight; more decompositions exist.
