Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543064, here are decompositions:

73 + 31542991 = 31543064
97 + 31542967 = 31543064
127 + 31542937 = 31543064
277 + 31542787 = 31543064
337 + 31542727 = 31543064
367 + 31542697 = 31543064
433 + 31542631 = 31543064
541 + 31542523 = 31543064

Showing the first eight; more decompositions exist.
