Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66242, here are decompositions:

3 + 66239 = 66242
73 + 66169 = 66242
139 + 66103 = 66242
313 + 65929 = 66242
433 + 65809 = 66242
523 + 65719 = 66242
541 + 65701 = 66242
613 + 65629 = 66242

Showing the first eight; more decompositions exist.
