Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542626, here are decompositions:

13 + 31542613 = 31542626
67 + 31542559 = 31542626
79 + 31542547 = 31542626
103 + 31542523 = 31542626
139 + 31542487 = 31542626
229 + 31542397 = 31542626
397 + 31542229 = 31542626
463 + 31542163 = 31542626

Showing the first eight; more decompositions exist.
