Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556602, here are decompositions:

101 + 31556501 = 31556602
113 + 31556489 = 31556602
179 + 31556423 = 31556602
293 + 31556309 = 31556602
353 + 31556249 = 31556602
359 + 31556243 = 31556602
401 + 31556201 = 31556602
461 + 31556141 = 31556602

Showing the first eight; more decompositions exist.
