Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540004, here are decompositions:

37 + 31539967 = 31540004
73 + 31539931 = 31540004
103 + 31539901 = 31540004
241 + 31539763 = 31540004
277 + 31539727 = 31540004
421 + 31539583 = 31540004
673 + 31539331 = 31540004
733 + 31539271 = 31540004

Showing the first eight; more decompositions exist.
