Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177740, here are decompositions:

61 + 177679 = 177740
139 + 177601 = 177740
151 + 177589 = 177740
229 + 177511 = 177740
307 + 177433 = 177740
313 + 177427 = 177740
331 + 177409 = 177740
421 + 177319 = 177740

Showing the first eight; more decompositions exist.
