Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523594, here are decompositions:

73 + 31523521 = 31523594
127 + 31523467 = 31523594
367 + 31523227 = 31523594
373 + 31523221 = 31523594
433 + 31523161 = 31523594
463 + 31523131 = 31523594
541 + 31523053 = 31523594
607 + 31522987 = 31523594

Showing the first eight; more decompositions exist.
