Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488722, here are decompositions:

103 + 31488619 = 31488722
229 + 31488493 = 31488722
241 + 31488481 = 31488722
613 + 31488109 = 31488722
631 + 31488091 = 31488722
691 + 31488031 = 31488722
709 + 31488013 = 31488722
919 + 31487803 = 31488722

Showing the first eight; more decompositions exist.
