Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488362, here are decompositions:

151 + 31488211 = 31488362
229 + 31488133 = 31488362
271 + 31488091 = 31488362
331 + 31488031 = 31488362
349 + 31488013 = 31488362
421 + 31487941 = 31488362
811 + 31487551 = 31488362
823 + 31487539 = 31488362

Showing the first eight; more decompositions exist.
