Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541096, here are decompositions:

79 + 31541017 = 31541096
157 + 31540939 = 31541096
229 + 31540867 = 31541096
283 + 31540813 = 31541096
313 + 31540783 = 31541096
373 + 31540723 = 31541096
397 + 31540699 = 31541096
439 + 31540657 = 31541096

Showing the first eight; more decompositions exist.
