Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552602, here are decompositions:

13 + 31552589 = 31552602
23 + 31552579 = 31552602
113 + 31552489 = 31552602
173 + 31552429 = 31552602
181 + 31552421 = 31552602
199 + 31552403 = 31552602
251 + 31552351 = 31552602
293 + 31552309 = 31552602

Showing the first eight; more decompositions exist.
