Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7490, here are decompositions:

3 + 7487 = 7490
13 + 7477 = 7490
31 + 7459 = 7490
73 + 7417 = 7490
79 + 7411 = 7490
97 + 7393 = 7490
139 + 7351 = 7490
157 + 7333 = 7490

Showing the first eight; more decompositions exist.
