Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61286, here are decompositions:

3 + 61283 = 61286
157 + 61129 = 61286
229 + 61057 = 61286
349 + 60937 = 61286
367 + 60919 = 61286
373 + 60913 = 61286
397 + 60889 = 61286
523 + 60763 = 61286

Showing the first eight; more decompositions exist.
