Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588602, here are decompositions:

41 + 31588561 = 31588602
79 + 31588523 = 31588602
109 + 31588493 = 31588602
131 + 31588471 = 31588602
139 + 31588463 = 31588602
163 + 31588439 = 31588602
233 + 31588369 = 31588602
251 + 31588351 = 31588602

Showing the first eight; more decompositions exist.
