Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498602, here are decompositions:

11 + 31498591 = 31498602
43 + 31498559 = 31498602
53 + 31498549 = 31498602
61 + 31498541 = 31498602
73 + 31498529 = 31498602
89 + 31498513 = 31498602
103 + 31498499 = 31498602
131 + 31498471 = 31498602

Showing the first eight; more decompositions exist.
