Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541228, here are decompositions:

67 + 31541161 = 31541228
127 + 31541101 = 31541228
157 + 31541071 = 31541228
181 + 31541047 = 31541228
211 + 31541017 = 31541228
307 + 31540921 = 31541228
571 + 31540657 = 31541228
577 + 31540651 = 31541228

Showing the first eight; more decompositions exist.
