Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455602, here are decompositions:

103 + 31455499 = 31455602
193 + 31455409 = 31455602
331 + 31455271 = 31455602
379 + 31455223 = 31455602
463 + 31455139 = 31455602
499 + 31455103 = 31455602
571 + 31455031 = 31455602
631 + 31454971 = 31455602

Showing the first eight; more decompositions exist.
