Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61490, here are decompositions:

3 + 61487 = 61490
7 + 61483 = 61490
19 + 61471 = 61490
73 + 61417 = 61490
109 + 61381 = 61490
127 + 61363 = 61490
151 + 61339 = 61490
157 + 61333 = 61490

Showing the first eight; more decompositions exist.
