Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541348, here are decompositions:

67 + 31541281 = 31541348
79 + 31541269 = 31541348
277 + 31541071 = 31541348
331 + 31541017 = 31541348
409 + 31540939 = 31541348
691 + 31540657 = 31541348
859 + 31540489 = 31541348
877 + 31540471 = 31541348

Showing the first eight; more decompositions exist.
