Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461602, here are decompositions:

31 + 31461571 = 31461602
79 + 31461523 = 31461602
199 + 31461403 = 31461602
241 + 31461361 = 31461602
349 + 31461253 = 31461602
373 + 31461229 = 31461602
379 + 31461223 = 31461602
409 + 31461193 = 31461602

Showing the first eight; more decompositions exist.
