Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64990, here are decompositions:

53 + 64937 = 64990
71 + 64919 = 64990
89 + 64901 = 64990
113 + 64877 = 64990
137 + 64853 = 64990
173 + 64817 = 64990
179 + 64811 = 64990
197 + 64793 = 64990

Showing the first eight; more decompositions exist.
