Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452602, here are decompositions:

3 + 31452599 = 31452602
19 + 31452583 = 31452602
31 + 31452571 = 31452602
73 + 31452529 = 31452602
109 + 31452493 = 31452602
151 + 31452451 = 31452602
421 + 31452181 = 31452602
523 + 31452079 = 31452602

Showing the first eight; more decompositions exist.
