Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461526, here are decompositions:

3 + 31461523 = 31461526
113 + 31461413 = 31461526
233 + 31461293 = 31461526
347 + 31461179 = 31461526
353 + 31461173 = 31461526
479 + 31461047 = 31461526
599 + 31460927 = 31461526
647 + 31460879 = 31461526

Showing the first eight; more decompositions exist.
