Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488602, here are decompositions:

109 + 31488493 = 31488602
139 + 31488463 = 31488602
331 + 31488271 = 31488602
571 + 31488031 = 31488602
661 + 31487941 = 31488602
823 + 31487779 = 31488602
1021 + 31487581 = 31488602
1051 + 31487551 = 31488602

Showing the first eight; more decompositions exist.
