Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543124, here are decompositions:

157 + 31542967 = 31543124
181 + 31542943 = 31543124
313 + 31542811 = 31543124
337 + 31542787 = 31543124
397 + 31542727 = 31543124
421 + 31542703 = 31543124
577 + 31542547 = 31543124
601 + 31542523 = 31543124

Showing the first eight; more decompositions exist.
