Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459260, here are decompositions:

37 + 31459223 = 31459260
43 + 31459217 = 31459260
59 + 31459201 = 31459260
61 + 31459199 = 31459260
109 + 31459151 = 31459260
127 + 31459133 = 31459260
137 + 31459123 = 31459260
149 + 31459111 = 31459260

Showing the first eight; more decompositions exist.
