Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487786, here are decompositions:

29 + 33487757 = 33487786
53 + 33487733 = 33487786
179 + 33487607 = 33487786
443 + 33487343 = 33487786
467 + 33487319 = 33487786
509 + 33487277 = 33487786
593 + 33487193 = 33487786
599 + 33487187 = 33487786

Showing the first eight; more decompositions exist.
