Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559468, here are decompositions:

67 + 31559401 = 31559468
97 + 31559371 = 31559468
151 + 31559317 = 31559468
229 + 31559239 = 31559468
307 + 31559161 = 31559468
337 + 31559131 = 31559468
397 + 31559071 = 31559468
541 + 31558927 = 31559468

Showing the first eight; more decompositions exist.
