Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494284, here are decompositions:

37 + 31494247 = 31494284
43 + 31494241 = 31494284
127 + 31494157 = 31494284
193 + 31494091 = 31494284
433 + 31493851 = 31494284
463 + 31493821 = 31494284
541 + 31493743 = 31494284
607 + 31493677 = 31494284

Showing the first eight; more decompositions exist.
